[U-Boot] Warning NetReceive(): Make sure packet buffers start on an even address
Hi, The network layer currently handles packets with c-structures overlayd on the packets. NetReceive() will fail to correctly parse packets that are not word aligned (at least on ARM cpus). Just figured that out debugging the enc28j60 driver. Which had no fault except for having the receive packet buffer on an odd address :) Instead of: static unsigned char buffer[ENC_MAX_FRM_LEN]; The following works fine: static unsigned long lbuffer[ENC_MAX_FRM_LEN/4]; #define buffer ((unsigned char *)lbuffer) Is there a more elegant way of forcing a char array to start on an even address?

Re: [U-Boot] Warning NetReceive(): Make sure packet buffers start on an even address
Wolfgang Denk schrieb: static unsigned char buffer[ENC_MAX_FRM_LEN] __attribute__ ((aligned(4))); Thanks, sometimes the very obvious is hidden behind a large wooden board :) Or, probably even better, use malloc() to allocate the buffer. For each received packet? Could do that, but its not worth it. Received packets are queued in the 6K RAM of the enc28j60. I'll see if the enc can be made to ignore broadcast packets, otherwise it might get tough either way on a busy Windows network . Or are you aware of any need to hand over broadcast packets into NetReceive() ? Reinhard ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
[U-Boot] [PATCH] NET: move legacy enc28j60.c to sidetrack as enc28j60_lpc2292.c
This patch is required before the upcoming new enc28j60 driver using SPI framework patch can be applied: - Move legacy enc28j60.c to enc28j60_lpc2292.c. - Change Makefile and the two affected boards' definition files. Tested with ./MAKEALL ARM7 that both boards still compile.

Chris Isbell schrieb: Or are you aware of any need to hand over broadcast packets into NetReceive() ? I am stepping into the middle of this, so the following may be totally misguided... BOOTP/DHCP servers can send broadcast packets. I have just tried this with a Windows DHCP server the the DHCP response was broadcast. Thanks for the info! That sounds like typical Windows (%@#*) Duly noted, broadcast reception is configurable by #define now.

Martin Krause schrieb: Hi all, Some time ago I modified the current encc28j60 driver to use the generic SPI api and to work with CONFIG_NET_MULTI. It was for a project not part of mainline U-Boot (and a bit of a hack), so I didn't post the patches on the mailing list. Reinhard, if you are interested, I could send you my patch, or post it on the mailing list. Yes, of course, at your discretion to the list, but if it is not yet in acceptable patch format it will suffice to send it to me. I will try to make it work on our AT91 based board (as a 2nd LAN interface, so CONFIG_NET_MULTI will be really required) and later submit a patch if all goes well.

The grepenv command this patch adds can be used in lieu of printenv to facilitate searching. grepenv works like printenv but limits its output only to environment strings (variable name and value pairs) that match the user specified substring. My five cents to this: this addition command should be optional (#ifdef) anyway... Thanks, but I will not apply thjis. I'm in the process of resturcturing the whole environment handling. The new implementation will use a hash table for internal storage, so this code would no longer apply then. Please wait a bit for me to publish the new code, and then try to reimplement it in the new environment. Will be there a means to mark variables as non-saveable, example if one does a bootp/dhcp and a saveenv afterwards, ip-address, filesize etc. are saved as well, which makes absolutely no sense. Neither does saving the ethaddr when it is created from VPD data :) Reinhard ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
[U-Boot] cmd_date.c error or itention?
Hi,
cmd_data.c codes the following:
case 2: /* set date time */
if (strcmp(argv[1],reset) == 0) {
puts (Reset RTC...\n);
rtc_reset ();
} else {
/* initialize tm with current time */
rcode = rtc_get (tm);
if(!rcode) {
/* insert new date time */
if (mk_date (argv[1], tm) != 0) {
puts (## Bad date format\n);
break;
}
/* and write to RTC */
rcode = rtc_set (tm);
if(rcode)
puts(## Set date failed\n);
} else {
puts(## Get date failed\n);
}
}
/* FALL TROUGH */
Now I have implemented rtc_get() such that it returns an error code
when the time is corrupt/has never been set.
However the if(!rcode) then prevents the time to be set!
Is that intentional and rtc_get() should never return an error ??
Or is it an oversight, and a patch would be welcome ?

[U-Boot] [PATCH] AT91SAM9260/9XE: add support for MultiMedia Card Interface (MCI)
This patch adds support for the Atmel MultiMedia Card Interface (MCI)
in AT91SAM9260 and AT91SAM9XE SoCs and preserves the original support
for the AVR32AP700x SoCs.
It patches the original atmel_mci.c driver to remove byte order and
toolchain dependencies and makes it a common MCI driver for
Atmels AVR32AP7000 and AT91SAM9260 based SoCs.
The driver itself is not specific to those SoCs and should work with
other Atmel devices having an identical MultiMedia Card Interface (MCI),
provided the functions get_mci_clk_rate() and SoC_mci_hw_init() are
defined.
Tested on AT91SAM9XE-EK (AT91SAM9XE512)
Tested on ATNGW100 (AVR32AP7000)

[U-Boot] AT91SAM9xxx SDCard/MMC support?
Hello, apparently none of the mainstream u-boot designs use SDCard/MMC. It appears that this task should not be a huge problem, the MCI for both AVR32 and AT91SAM9 seems to be identical (and MCI on AVR32 works). But before I perhaps reinvent anything already done, I prefer to ask here. Also any input what obstacles have been found would be appreciated. I need the support for 9260/9G20/9XE.

After some hacking I get the following results: TOP9000 mmc init mmc: bus_hz is 99328000, setting clock 15 Hz, block size 512 mmc: requested clock 15 is too low; setting CLKDIV to 255; resulting clock is 194000 mmc: CMD0 0x0 (flags 0x0) mmc: status 0xc0e5 mmc: CMD0 0x0 (flags 0x100) mmc: status 0xc0e5 mmc: CMD55 0x0 (flags 0x1040) mmc: status 0xc0e5 mmc: response: 0120 mmc: CMD41 0x10 (flags 0x41) mmc: status 0x0004c0e5 mmc: response: 00ff8000 mmc: CMD55 0x0 (flags 0x1040) mmc: status 0xc0e5 mmc: response: 0120 mmc: CMD41 0x10 (flags 0x41) mmc: status 0x0004c0e5 mmc: response: 80ff8000 mmc: CMD2 0x0 (flags 0x80) mmc: status 0xc0e5 mmc: response: 19445953 4d495344 1073 f30054bb Manufacturer ID: 19 OEM/Application ID:4459 Product name: SMISD Product Revision: 1.0 Product Serial Number: 29683 Manufacturing Date:05/04 mmc: CMD3 0x0 (flags 0x1040) mmc: status 0xc0e5 mmc: response: b3680500 SD Card detected (RCA 45928) mmc: CMD9 0xb368 (flags 0x1080) mmc: status 0xc0e5 mmc: response: 005e0032 1f5983d0 6db7bf9f 9645 CSD data: 005e0032 1f5983d0 6db7bf9f 9645 CSD structure version: 1.2 MMC System Spec version: 12 Card command classes:3d0 Read block length: 256 Supports partial reads Write block length: 1 Does not support partial writes Does not support group WP Card capacity: 131072000 bytes File format:1/2 Write protection: permanent mmc: Using 983040 cycles data timeout (DTOR=0x6f) Card does not support 512 byte reads, aborting. No MMC card found It IS a 1 GB Card, and sure has 512 Byte sectors (it worked well on the ATNGW100) with the same driver source. What I notice is that the current driver (atmel_mci.c) nowhere sets the MMCI_SDCR register, therefore using the bus in 1 bit mode. But that is the case in the AVR32 case as well, and there MCI did work... ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

[U-Boot] [PATCH] Fix (null) problem for AVR32 boards
Currently the U-Boot address ranges for AVR32 boards are
printed like this:
U-Boot code: (null) - 0001183c data: 000188e8 - 0004e9b0
This patch fixes this to print:
U-Boot code: - 0001183c data: 000188f8 - 0004e9c0

Will it care sometime in the future? :) The second problem is that I cannot seem to undo my previous commit in my tree, so any changes I do to my source would come out as a second patch. Would that be accepted? Or do you know what must be done that GIT will issue a new patch with the current and the new changes in one patch? I generate the patches by after editing: git commit -m message git format-patch origin what to do to return to after editing, do new edits and generate a new, single patch?

[U-Boot] Warnings when compiling for AVR32 boards
During ./MAKEALL avr32 at least my toolchain gives the following warnings for every board: Configuring for atstk1002 board... atmel_usart.c:21:2: warning: #warning Please update to use C structur SoC access ! cmd_bdinfo.c: In function 'do_bdinfo': cmd_bdinfo.c:295: warning: format '%d' expects type 'int', but argument 2 has type 'long unsigned int' textdata bss dec hex filename 915877136 211712 310435 4bca3 ./u-boot same for all boards atmel_usart.c: that is more or less a TODO warning, it should probably be removed or the structure approach be implemented. And is it wise to directly pointer access hardware, even if the AVR32 hardware allows that without cache problems? cmd_bdinfo.c: this is because printf (baudrate= %d bps\n, bd-bi_baudrate); but AVR32 bd_t has unsigned long bi_baudrate and there is no explicit case for avr32 architecture, so the code under /* ! PPC, which leaves MIPS */ is compiled and used! The current architecture specific #if chain in cmd_bdinfo.c is as follows: #ifndef CONFIG_ARM /* PowerPC and other */ #ifdef CONFIG_PPC #elif defined(CONFIG_NIOS2) /* Nios-II */ #elif defined(CONFIG_MICROBLAZE) /* ! PPC, which leaves Microblaze */ #elif defined(CONFIG_SPARC)/* SPARC */ #elif defined(CONFIG_M68K) /* M68K */ #elif defined(CONFIG_BLACKFIN) #else /* ! PPC, which leaves MIPS */ AVR32 falls into here #endif /* MIPS */ #else /* ARM */ #endif /* CONFIG_ARM XXX */ Would it not be better to include ARM in the #elif chain as well, and of course add AVR32 in a similiar way: #if defined(CONFIG_PPC) #elif defined(CONFIG_NIOS2) #elif defined(CONFIG_MICROBLAZE) #elif defined(CONFIG_SPARC) #elif defined(CONFIG_M68K) #elif defined(CONFIG_BLACKFIN) #elif defined(CONFIG_MIPS) #elif defined(CONFIG_AVR32) #elif defined(CONFIG_ARM) #else #error a case for this architecture does not exist #endif I can rework that and submit a patch, but I cannot MAKEALL all the architectures. However the changes should be straightforward and involve little risk breaking something. Reinhard ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

Re: [U-Boot] AVR32 AP700x - I2C somewhere?

Hi,
Dear Reinhard Meyer,
has anyone started or completed work on an I2C driver for AP7000x?
No ...
If not, I am at least going to make SOFT I2C defines to read VPD from an
At24C64 EEPROM.
But I've working soft-i2c here. There are still some other examples in
u-boot how to interface a at24xx eeprom.
Thank you. That worked to verify my setup.
I was fooled by the AtTiny on the NGW100 which does try to slow I2C
Transfers by pulling SCL low.
That feature however is NOT honored by the SOFT_I2C driver.
So accesses to my At24C64 had to fail. After removing the AtTiny it
works fine :)
custom board config file:
---8---
/* i2c definitions */
#define CONFIG_SOFT_I2C
#if defined(CONFIG_SOFT_I2C)
#define DEBUG_I2C
#ifndef __ASSEMBLY__
#include asm/arch/portmux.h
#define MEDUCORE_SDA_PIN 6
#define MEDUCORE_SCL_PIN 7
#define I2C_ACTIVEportmux_select_gpio(PORTMUX_PORT_A,
(1MEDUCORE_SDA_PIN), PORTMUX_DIR_OUTPUT|PORTMUX_INIT_LOW)
#define I2C_TRISTATE portmux_select_gpio(PORTMUX_PORT_A,
(1MEDUCORE_SDA_PIN), PORTMUX_DIR_INPUT|PORTMUX_OPEN_DRAIN)
The functions ACTIVE and TRISTATE are not required when the Pins are
initialized OUTPUT and OPENDRAIN as follows:
int board_early_init_f(void)
{
...
#ifdef CONFIG_CMD_I2C
// first select SCL and SDA gpio
portmux_select_gpio(PORTMUX_PORT_A,(1SDA_PIN),
PORTMUX_DIR_OUTPUT|PORTMUX_INIT_LOW|PORTMUX_OPEN_DRAIN);
portmux_select_gpio(PORTMUX_PORT_A,(1SCL_PIN),
PORTMUX_DIR_OUTPUT|PORTMUX_INIT_LOW|PORTMUX_OPEN_DRAIN);
// initialize i2c
i2c_init(1000, 0x27);
#endif
return 0;
}
The I2C Bus by definition is a wired-or bus, all devices must have open
drain outputs for SDA and SCL!
Best Regards,
Reinhard
