I can confirm that the problem is present on the pandaboard Rev B1 version as well. When Lokesh mentioned the bisect, I checked out mainline and tried booting from an SD card - it didn't come up. :( removing the lines mentioned got it working again. My usual boot device is USB and I use the omap4b

Hello Chao, (cc R.Sricharan from TI) Quite frankly, I have no idea why your pandaboard fails to work if CONFIG_SYS_ENABLE_PADS_ALL isn't defined in the omap4_common.h file. From the logs this patch was committed on 13/June/2012 by R.Sricharan. He might have a better explanation so I'm adding him

Hi Abraham, I finally got it working by adding "#define CONFIG_SYS_ENABLE_PADS_ALL" in u-boot/include/configs/omap4_common.h! This is removed by default in v2013.10. Do you know why? Thank you! On Sun, Nov 24, 2013 at 10:11 PM, Abraham V. wrote: > Hello Chao, > > That sounds odd. Can you try dow

Hi Abraham, Thank you very much for your detailed reply! But I think I can rule out the three possible problems you mentioned. 1. The cross compiler should be fine. Because I use it all the time to compile kernel for pandaboard and it has never been a problem 2. I'm doing exactly what you suggeste

My company is designing a custom board that can be thought of as a derivative of the pandaboard. I believe we have Rev B1 with us in the office. Considering that you are not getting any debug messages on your serial console, I suspect one of the following; * your cross-compiler might have issues *

Hi, I'm trying to compile the latest u-boot for my Pandaboard Rev A2. The SD card was originally loaded with a working version of 12.04 linaro-unbunt-developer image. Early printk is enabled in the original image. I followed this guide (http://elinux.org/Panda_How_to_MLO_%26_u-boot) and here is w
