[beagleboard] Access GPIO/SPI etc. on Expansion Header
Hi, with its (freely programmable) expansion connector BeagleBoard Black seems to be a perfect thingy for embedded applications. Since I did not find anything suitable (only a Python library or some JavaScript-based things which all seem to be way to slow for my usage): Is there a (realtime-capable) library available that gives the possibility to access the expansion header and utilitise it's SPIs, digital IOs and PWM outputs? With "library" of course every piece of code is meant whatever is out there (so it can be kernel driver based for existing Linux variants, bare-metal code, whatever...)

[beagleboard] What is System Clock / CLK_M_OSC?
Hi, I try to generate an internal interrupt that occurs with 4 MHz frequency. Here I found an CPU-internal timer that can used via a prescaler and uses a System Clock / CLK_M_OSC as input. Now I can't find out what this CLK_M_OSC is on BeagleBone - is it 1GHz? If not: on which frequency is CLK_M_OSC running?

[beagleboard] Getting started with bare-metal programming on BBB
Hi, I plan to do some bare-metal programming with the BBB (mainly for personal reasons and to play with hard realtime environments, so please do not try to soften me up to use Linux ;-) As a first task and to get a feeling for the hardware I'd try to access the LEDs (configure the GPIOs they are connected with as digital output and write 0/1 to them). My question: is there a getting-started-guide for this? Or to go more in detail: - I already found the CPU manual at TI's pages - I found a compiler arm-none-eabi-gcc - is it the correct one? - I still need header files where register addresses for the CPU are predefined - I still need a description how to download my created binaries to the board so that they are started immediately (instead of the Linux-Distro) Any Ideas where I can find these things?

[beagleboard] Re: Getting started with bare-metal programming on BBB
I know there is a possibility to access PRU under linux but as stated above I DEFINITELY want to do some bare metal programming on the "naked" board. I already checked out TI's StarterWare and I'm open to use uboot prior to my own code...so I'll check the boards to find out what has to be changed in order to use it on BBB.

[beagleboard] Failed compiling GPIO-example of Starterware / unresolved symbol Entry
Hi,
I'm just doing some first steps in bare-metal programming of BeagleBone Black.
I downloaded Starterware and CCS vom TI, got the correct .gel file,
imported the GPIO-Example (LED-blinking) from Starterware into CCS,
adjusted the project settings to work with newer ARM compiler version
5.1.1 and tried to compile the whole thing.
Now CCS gives me an error
unresolved symbol Entry
This "Entry" thingy can be found in gpioLEDBlink.cmd:
SECTIONS
{
.text:Entry : load > 0x8000
But: why doesn't it compile? What do I have to change to compile the
whole thing successfully?
Thanks!

[beagleboard] Troubles starting bare-metal program from external SD card
Hi, I have some big troubles deploying the LED-blink-example from Starterware on an external Micro-SD card. That's what I have done: - format the card using the HP Disk utility - place MLO file on it - place file "app" (which contains the compiled blink-example) on the card - optionally place file "u-boot.img" (which contains the same) on the card On start up three LEDs on the board are lit, serial interface tells me something about "invalid partition 2" and nothing happens. For MLO and app I tried: - self compiled binaries (including some changes I found in TI-forum necessary for BBB) prepared with the TI-image-tool - the MLO and u-boot.img file from internal SD-card Result is always the same. Then I found information in BBB-Wiki to delete/rename the MLO file on internal SD-card. Now the three LEDs are no longer lit, serial debug console prints nothing more than "CC" - and my program still does not work. Any idea what I'm doing wrong?

Re: [beagleboard] Troubles starting bare-metal program from external SD card
The difference black/white is not a problem, I already modfied the related code in Starterware (there is a thread in TIs forum that describes what has to be done in order to make Starterware usable on BBB).

[beagleboard] Start Address of RAM on BBB?

[beagleboard] Select CLK_M_OSC as source for DMTimer (instead of 32 kHz clock)
Hi, I'm trying to set up a fast timer interrupt using CLK_M_OSC as clock source for DMTimer2. For initialising this I'm calling DMTimer2ModuleClkConfig() from Starterware code which itself seems to select CLK_M_OSC as source for the timer clock using following code: /* Select the clock source for the Timer2 instance. */ HWREG(SOC_CM_DPLL_REGS + CM_DPLL_CLKSEL_TIMER2_CLK) &= ~(CM_DPLL_CLKSEL_TIMER2_CLK_CLKSEL); HWREG(SOC_CM_DPLL_REGS + CM_DPLL_CLKSEL_TIMER2_CLK) |= CM_DPLL_CLKSEL_TIMER2_CLK_CLKSEL_CLK_M_OSC; while((HWREG(SOC_CM_DPLL_REGS + CM_DPLL_CLKSEL_TIMER2_CLK) & CM_DPLL_CLKSEL_TIMER2_CLK_CLKSEL) != CM_DPLL_CLKSEL_TIMER2_CLK_CLKSEL_CLK_M_OSC); As fas as I understand there CLK_M_OSC is choosen. Nevertheless the frequency/calling speed of my ISR tells me I'm still at 32 kHz clock, so CLK_M_OSC does not seem to be used. My whole initialisation code looks like this (and mainly comes from the Starterware examples): DMTimerModeConfigure(SOC_DMTIMER_2_REGS, DMTIMER_AUTORLD_NOCMP_ENABLE); DMTimerCounterSet(SOC_DMTIMER_2_REGS, 0xFFF9u); DMTimerReloadSet(SOC_DMTIMER_2_REGS, 0xFFF9u); DMTimer2ModuleClkConfig(); --> here CLK_M_OSC should be chosen... IntAINTCInit(); IntRegister(SYS_INT_TINT2, isr_xy2_100); IntPrioritySet(SYS_INT_TINT2, 0, AINTC_HOSTINT_ROUTE_IRQ); IntSystemEnable(SYS_INT_TINT2); IntMasterIRQEnable(); So...what could be wrong? Why isn't the fast clock source used?

Re: [beagleboard] Select CLK_M_OSC as source for DMTimer (instead of 32 kHz clock)
The Starterware initialisation function already reads back the flag for CLK_M_OSC, so that should fit. Multiplexing is not necessary for DMTimer 2 and 3, so I don't know what to set/check here. What is TRM?

Re: [beagleboard] Select CLK_M_OSC as source for DMTimer (instead of 32 kHz clock)
OK, it seems my counter/prescaler settings for initial and reload
count value are ignored or used for first shot only, so it seems
something is wrong in my initialisation code:
DMTimer2ModuleClkConfig();
IntMasterIRQEnable();
IntAINTCInit();
IntRegister(SYS_INT_TINT2, isr_func);
IntPrioritySet(SYS_INT_TINT2, 0, AINTC_HOSTINT_ROUTE_IRQ);
IntSystemEnable(SYS_INT_TINT2);
/* Load the counter with the initial count value */
DMTimerCounterSet(SOC_DMTIMER_2_REGS,0xFFF9);
/* Load the load register with the reload count value */
DMTimerReloadSet(SOC_DMTIMER_2_REGS, 0xFFF9);
/* Configure the DMTimer for Auto-reload and overflow mode */
DMTimerModeConfigure(SOC_DMTIMER_2_REGS, DMTIMER_AUTORLD_NOCMP_ENABLE);
DMTimerIntEnable(SOC_DMTIMER_2_REGS, DMTIMER_INT_OVF_EN_FLAG);
DMTimerEnable(SOC_DMTIMER_2_REGS);
And the ISR:
static void isr_func()
{
static int clockCtr=0;
static int ledCtr=0;
// DMTimerIntDisable(SOC_DMTIMER_2_REGS, DMTIMER_INT_OVF_EN_FLAG);
// DMTimerIntStatusClear(SOC_DMTIMER_2_REGS, DMTIMER_INT_OVF_IT_FLAG);
ledCtr++;
clockCtr++;
// some code here...
/* Re-enable the DMTimer interrupt */
// DMTimerIntEnable(SOC_DMTIMER_2_REGS, DMTIMER_INT_OVF_EN_FLAG);
}

BBB is for several reasons the best solution for me. And what I try to do is not as complex as it sounds, I just want to access some GPIOs, Ethernet and - perhaps - UART. All the other things like USB, LCD/HDMI, SPIs and whatever is available on the board is not required. Meanwhile I have some code running on it - most troubles have been caused by build problems due to poor Linux support of TIs Starterware.

[beagleboard] Load and execute PRU code from bare-metal application
Hi, after there is some experimental, bare-metal code now running smoothly on my BBB I plan to utilitise the PRU to do some realtime tasks (mainly do bit-banging on some GPIO outputs). Unfortunately documentation and examples seem to be very rare and the TRM is very detailled - to not to say sometimes much too detailled to get an overview about the whole story. There is some PRU code available at https://github.com/beagleboard/am335x_pru_package but the host-side code seems to expect a running Linux system. So my question: are there any examples/documentation available out there that show/describe how to - enable PR - load code into PRU - execute that code on PRU - exchange data between CPU und PRU (seems to be via some shared memory?) frwom within bare-metal code? Starterware itself seems to ignore the PRU part completely, nothing helpful there instead of an unused headerfile...

[beagleboard] Where is Angstrom-Linux stored?
Hi, I have a general problem in understanding the BBB and its boot process. With factory defaults BBB starts Angstrom Linux on power-up - correct? Now when one connects this board via USB and with no micro-SD-card plugged to a host computer, a drive is shown there which contains some files (MLO bootloader u-boot.img and some documentation). So my question here: where are these things stored? And where is the Linux-filesystem stored which does not appear within this drives data? I'd assume it has something to do with internal NAND-flash...but in this case the boot procedure of BBB is not clear to me - is the CPU itself able to read a FAT-formatted filesystem to start the MLO-bootloader? Or how else is booting done in this configuration?

[beagleboard] Wiring of switches on BBB
Hi, when I'm not wrong the boot-switch of the BBB is connected to GPIO0[22] so that it could be checked out of software using this input. Reset is connected to the reset line...and the power switch?

[beagleboard] "Forbidden" pins on P8 and P9
Hi, I'm doing some low-level bare-metal programming with the BBB and "abuse" the pins on P8 and P9 for different things. Thus I multiplex these pins to the functions I need (mainly GPIOs). As far as I understood it some of these pins are used for SD-card reader and eMMC and therefore should not be used and multiplexed to something different. In case my understanding is correct: is there an overview which pins are affected by SD-Card and eMMC? LCD/HDMI is not used by my application and therefore can be overwritten but CD and MMC should work in every case.

Re: [beagleboard] "Forbidden" pins on P8 and P9
Hi, I already know the pinout-listing of the BeagleBone Black but this does not seem to solve my problem. Depending on the choosen pin-mux-mode the eMMC signals can appear on different pins on P8/P9. So I need to know the real wiring, means which pins on P8/P9 are electrically connected to CPU and eMMC. Unfortunately I do not understand the wiring diagram good enough to find the answer there. So I hoped there is a pinout-listing available somewere that contains the information which of the pins are also wired to eMMC...

[beagleboard] Enable Cape via SYS_RESETn?
Hi, just to verify some things before I order design of my capes: according to http://elinux.org/Beagleboard:BeagleBoneBlack#Expansion_Header_Usage it is not allowed to have an input signal on any of the GPIO-pins during power-up or during boot. Resulting from that I think about using SYS_RESETn as signal to enable my capes. So my question: - which current can be pulled out ot SYS_RESETn / how much GPIO-inputs can I drive with this signal? - when SYS_RESETn is HIGH the GPIOs may not be programmed as input (because firmware is not fully started at this point) but the Cape-hardware possibly sets an input signal to them (because SYS_RESETn already enabled it). Is this a problem? Can I use SYS_RESETn to enable input signals too or should I use an additional GPIO as output which enables such signals much later than SYS_RESETn would do that?

Re: [beagleboard] Enable Cape via SYS_RESETn?
Thanks. And just to verify my second question: When SYS_RESETn is high but the GPIOs are not multiplexed since the firmware is not fully started: is it allowed to have a HIGH-signal on a GPIO pint that is not already programmed as input?

[beagleboard] Access eMMC FAT drive
Hi, I'm developing a bare-metal application on my BBB that makes use of TI's Starterware. There everything seems to be contained, except one thing: file system access to internal flash (eMMC). So my question: is there any example code available that demonstrates how to access the eMMC FAT-partition without having huge dependencies to some other things? Means some code that can be used within a bare-metal environment?

Just as an update to my previous mail: I got freedback from three companies offering BBBs on alibaba.com. All of them told me they are selling original boards, none of them is manufacturing clones. Since all of them promise to ship within a few days I think we now know where all the cheap boards are gone to.

Then let's bring up the old question: why not offering a higher priced variant of BBB that can be manufactured in higher numbers? I'd be willing to pay up to US$ 80 for a BBB that is REALLY available. You of course could still offer the low-cost BBBs for the intended market in parallel - with current availability. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

[beagleboard] Access FatFS on eMMC
Hi, since the answer in TIs Starterware forum is only a useless "you have to implement it in MMCSDLIB" I ask it here: Starterware does provide example code that shows how to access FatFS on SD card but nothing for eMMC. So has anybody been able to get it running for eMMC? Any examples available somewhere? Btw: Linking to some Linux driver does not help very much (at least me) since they are TOO different to Starterware bare metal code.

[beagleboard] Re: How to learn to use TCP/IP on TI Sitara Starter Kit (Beaglebone)?
What is running on your board exactly? When it is an Linux/Ubuntu, there is nothing special, you can use any TCP/IP/sockets documentation for Linux that is out there. When you are using StarterWare bare metal code, you will find it makes use of lwIP. There is a extensive documentation available from this project and StarterWare comes with some examples about how to use it. In this special case it is not programming with a standard socket-API but access to RAW lwIP functions. Am Freitag, 26.

[beagleboard] Problems with BBB USB serial communication and Windows 10
Hi, I'm running a StarterWare 2 based application on an BBB which makes use of a USB serial interface implementation based on the StarterWare example and by using a .inf-File which is similar to "usb_dev_serial.inf" which was provided by TI in same StarterWare package. Of course VID and PID have been changed according to my own USB serial interface implementation. This works well with all Windows-versions up to 7 (8.x was never tested) and also with all Linux variants. But now with Windows 10 there is a problem which was reported by different users of this application: - opening of the serial interface often fails, simple repeating of the procedure then is successful latest after 10 tries - sometimes an already opened connection seem to be corrupted, means there is no more communication possible, host application needs to be closed, device needs to be restarted - but after this, the same COM-port is available again, Windows does not change numbering So: is anything known about such problems in Windows 10 ? Perhaps are there any changes necessary in an INF-file or in USB serial interface code to make it work with Windows 10? Is there anything similar known from the Linux Kernel of the BBB? Any hint or idea is welcome! -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
