Re: [U-Boot] Help needed on Colibri T20 - Iris Board
Hi guys, Here's the situation: We applied the following patches to an original u-boot source code (2011.09 version): [U-Boot] [PATCH 1/2] Tegra2: Make XTal speed configurable [U-Boot] [PATCH 2/2] Tegra2: Add support for Toradex Colibri T20 board And we use the antmicro patches for the Colibri T20 available on http://antmicro.com/blog.html (category ARM) Their patches are used to add the USB drivers for using the USB-to-Ethernet port. Then, we take the following patches: [U-Boot] [PATCH v2 0/8] Tegra2: Implement SPI flash and saved environment The problem is that this patch is for the Seaboard. We adapted it for the Iris Board but this ain't working. We wonder if this patch is the right one. 2012/1/11 Simon Glass s...@chromium.org Hi Stéphane, On Wed, Jan 11, 2012 at 1:52 AM, Stéphane Carvalho carvalho.steph...@gmail.com wrote: We are 2 engineering students from Fribourg, Switzerland working on a embedded systems project.

OK. There is a USB series on the list also. I can see a tar file on that web page but didn't look at it. I presume it works for you ok so that is fine. Then, we take the following patches: [U-Boot] [PATCH v2 0/8] Tegra2: Implement SPI flash and saved environment The problem is that this patch is for the Seaboard. We adapted it for the Iris Board but this ain't working. We wonder if this patch is the right one. Well the series includes the driver support but also turns on the environment options in seaboard.h. So at the least you would need to turn these options on in your config file. Also check that the pinmux is being set in tegra2_spi.c. The final few patches to do this cleanly for Seaboard were NAKed (NS16550 changes and buffering) so this might be slightly different on your platform. It looks like you use UARTA so won't have the SPI/UART conflict, but you still need to make sure that SPI's pinmux is enabled.

Hi Wolfgang, they don't have any storage media. They PMed me and I explained to them. Anyway, I suspect we won't be getting any further here as they decided to use out-of- tree port (sadly).
