Hi Community,
I'm working on a proprietary board based on L138 processor and on Linux OS.
In order to perform first time software download (u-boot, kernel etc...) and sw upgrade of the boards I'm building a system booting from SD card and at u-boot level or kernel level launch a lot of scripts performing software download.
At the moment kernel, root-FS and application file system are successfully downloaded the problem is u-boot and bootloader. I can download them but board doesn't start. Only downloading with sfh_OMAP-L138.exe using the following command: sfh_OMAP-L138.exe -flash -targetType OMAPL138 -flashType NAND -p com1 arm-nand-ais.bin u-boot-uart1-03.bin my board boot correctly.
Using sfh_OMAP-L138.exe i can see it place the two binary in the command line at their location that is 0x20000 the ais and 0x40000 the u-boot furthermore i can see few byte at 0xc0000
Now which is the right way from u-boot prompt or kernel prompt to place u-boot in NAND flash ? Where and how i have to put UBL, AIS and u-boot ?
Hope someone can help
Thanks
Regards
Luca
