Dear All,
I’m about to add some modifications to U-Boot on the Jetson Nano 2GB board. I’m working with Yocto and usually do the following steps to test a given modification:
bitbake u-boot-tegra -C compile -f
bitbake core-image-weston
then extract tegraflash and execute “sudo ./doflash.sh --spi-only”
This whole process takes several minutes to complete. Is there maybe a faster way of rebuilding and updating U-Boot in the SPI flash?
Thanks!
When I update the devicetree only there is a slightly faster way. After Linux has been built the .dtb file can be written directly to the SPI flash with the “flash.sh -k DTB …” command. (flash.sh comes from L4T-tegra210-32.5.2-r0/Linux_for_Tegra) Isn’t there something similar for U-Boot?
