Part Number:OMAPL138B-EP
Hello,
I am currently attempting to configure and send a U-Boot image over UART for the OMAPL138 Processor to execute.
This wiki page for the OMAP-L138 has several files linked to it, including a serial loader host that can presumably be used to send an AIS image file over UART to the board being used.
We have a .ais file and u-boot.bin file that we can send over the UART connection that we use to resurrect a dead board. For this, we use the sfh_OMAP-L138 tool after setting the processor to UART boot. In this configuration, the .ais file and u-boot.bin are copied to the NOR flash and then used for subsequent boots.
What I want to do, however, is send the first stage bootloader (the AIS file) and the u-boot.bin via the UART and boot directly from memory. It seems like the first stage bootloader needs to be modified to jump to a location in memory for the second stage (u-boot.bin) instead of using the SPI NOR, but I can't find any documentation on how to modify an AIS file. What resources exist for modifying the AIS bootloader and configuring it for UART booting?
Any clarification or advice on this process would be greatly appreciated.
Thank you,
- Daniel
