Hi Tom,
I was trying the latest master branch for ti8148 evm to boot from SD card, following are the steps which I followed:
1: make ARCH=arm CROSS_COMPILE=arm-cortex_a8-linux-gnueabi- clean
distclean
2: make ARCH=arm CROSS_COMPILE=arm-cortex_a8-linux-gnueabi-
ti814x_evm_config
3: make ARCH=arm CROSS_COMPILE=arm-cortex_a8-linux-gnueabi-
Copy the MLO and u-boot.bin to SD card boot partition which is bootable, I see no prints coming from the 1st stage bootlaoder, cant debug it as I don’t have access to JTAG.
Any pointers is this code tested ?
First, you need to use u-boot.img not u-boot.bin. Second, which PG do you have on the board? We only have support for PG1.0 today and not PG2.0 as Matt did the initial bring-up and only has a PG1.0 board. The code should be easily ported from the old PSP tree to support PG2.0 however.
What about DM816x support? Mainline u-boot have anything for it? We finally have Linux 4.2.3 running on our board with .dts support. Now I'm starting the task of getting a mainline u-boot to work so we can get rid of the legacy dtb being part of kernel.
Well, the ti816x support we have today should be a good starting point at least for the "DM" variant of the chip. I forget which one of the boards I have technically but I _think_ the differences are high level enough that for U-Boot it's OK.
