[beagleboard] Change USB OTG mode to USB host and USB peripheral

Hi I am using a custom hardware which is based on Beaglebone black. The hardware difference between BBB and our board is that USB0 is changed to work in host mode and USB1 in peripheral mode. I need to make the necessary changes in kernel as well to make this work. I have built the kernel and

Hi, I have a beagleboard rev 4, that I have newer used since it was new. Now I have tried to start it up for the first time. I have not added any memory card and no Linux image yet. Instead I have plugged in power via USB, and the serial cable between PC and the beagleboard. I have tried to pl

There are four different BeagleBoards, can you give us some more information on the board? There also was not a rev 4 made. We use letters A,B,C followed by numbers on our revisions. http://www.elinux.org/Beagleboard:Main_Page Gerald On Thu, Nov 5, 2015 at 6:52 AM, wrote: > Hi, > I have a bea

Re: [beagleboard] SPI BBB Master, BBB Slave

Hi Ravi, This is something I’m currently working on. However, for your application, why do you need to use SPI? Surely you could use IP Sockets or UART to achieve the same thing. Also, McASP has both master and slave support through the sound subsystem. Specifically you can use spdif_receiver.c

[beagleboard] Console output garbled?

All of a sudden, I'm getting garbled console output. Not always, but frequently. This is a "fresh" BBB that I got a while back but haven't used. After I fried my other BBB, I moved everything over to this one, but didn't flash the eMMC. If I boot without an SD card, it's garbled. If I boot with

Re: [beagleboard] Console output garbled?

Do you have the option to lock it in the basic ASCII 7 bit character set? That would likely solve the problem. The problem with Teraterm is that the BBB will sometimes put out some gibberish or perhaps some non-printing control characters at the start of the console output (don't know why) and it

I have set up SPI on my BBB (spidev_test works fine) and have compiled/installed the AT25 SPI EEPROM kernel module. I am missing the knowledge/piece that allows me to access the AT25 using the read/write calls. The at25 spi eeprom is a proxy/training ground for a much more complex spi device in
