Hi,
We have developed our own hardware with a DM3730 module from Embest (Mini8510), which is similar to Beagle board. It is running on kernel 2.6.32, but we would like to upgrade to 2.6.37. I have made all needed modifications based on beagle files to match our hardware - however, when boot with the new kernel, I get no output after "Starting kernel...". According to this guide:
http://processors.wiki.ti.com/index.php/Kernel_-_Common_Problems_Booting_Linux
... it is most likely because the output is directed to the wrong uart. The config files under arch/arm/configs seems to be different in the new kernel, and I cannot find
# CONFIG_OMAP_LL_DEBUG_UART1 is not set # CONFIG_OMAP_LL_DEBUG_UART2 is not set CONFIG_OMAP_LL_DEBUG_UART3=y
... as in the old versions. Also, in "menuconfig" I am not able to find "Low-level debug console UART"
But I cannot see why I should need to change this. The Beagle board uses UART3 for debug (as do our hardware) and when using the new kernel, it should not change, so maybe there is another issue?
I have also tried to compile for Beagle board expecting to see "Error: unrecognized/unsupported machine ID", but also here I see nothing after "Starting kernel...".
At the moment I have no clue where to look, so any help will be appreciated.
Thanks,
Christian
