In fact I'm using OMAPL138 platform and I think that it is not UBL that is copying kernel under that platform. I have been able to find the kernel image relocation in cmd_bootm.c but that is not the inital copy. I added printf/puts into the code to find where exactly it happens and my last print

Hi Nicolas, > I'm using OMAP-L138 (ARM based) with NOR flash and I'll like to know in > which file uboot copies kernel from NOR to RAM? This will be the UBL which runs before U-Boot gets a chance to run. Just before Stefano Babic's work on the dm365 platform all davinci U-Boot ports configured CO

Ok I would like to improve the copy of linux kernel from NOR to RAM. I would like to replace the current copy and use EDMA instead. I traced the uboot code but I can't find in which file (uboot source code) the copy (from NOR to RAM) takes place. Thanks. Regards, Nicolas On Mon, Aug 23, 2010
