I am following the Development Guide (28.1 Release) U-Boot Customization chapter to attempt to add CONFIG_RESET_TO_RETRY and CONFIG_BOOT_RETRY_TIME to give access to the bootretry environment variable. These configs are discussed in README.autoboot
Building U-Boot seems relatively straightforward. I added these defines to include/configs/p2371-2180.h and built the binaries using p2371-2180_defconfig. I know they are being built because if I include CONFIG_BOOT_RETRY_TIME without CONFIG_RESET_TO_RETRY I get a warning about not including both variables.
The next step is to copy the resultant binaries into the bootloader folder:
cp <uboot_src_dir>/u-boot{,.bin,.dtb,-dtb.bin} \
<your_L4T_root>/Linux_for_Tegra/bootloader/t210ref/p2371-2180/
And now flash the board:
sudo ./flash.sh p2371-2180 mmcblk0p1
Everything works, the board is flashed, but U-Boot doesn’t change. There’s no bootretry variable, bootdelay isn’t set to the right default value, and querying “version” on the command line still returns that the binary was built 2 months ago.
I’ve even tried doing just the bootloader with the same result.
sudo ./flash.sh -k EBT p2371-2180 mmcblk0p1
This is the output of the above command. I see nothing to indicate that it’s using the binaries in <your_L4T_root>/Linux_for_Tegra/bootloader/t210ref/p2371-2180/. Am I missing something?
