hi supporter,
In Orin chip, DRIVE OS , how to set in BCT(non-gpio bootmode) boot from B chain?
i did not see “u32_non_gpio_select_boot_chain”," u32_num_boot_chains " these two field in “tegra234-br-bct-auto-qspi.dts” file. force add these two field(value 1,2) in this file. after re-power the Orin the log still is print u32_non_gpio_select_boot_chain=0, u32_num_boot_chains =4. could you give some support for me? thanks!

hi SivaRamaKrishna,
Thanks, below is my main step
Step 1:
add boot chain selection and config nums
{TOP}/drive-foundation/platform-config/hardware/nvidia/platform/t23x/automotive/bct/common/bootrom/tegra234-br-bct-auto-qspi.dts
image
Step 2:
cd {top}/drive-foundation
./make/bind_partitions -d -g -b p3663-a01 linux -u ndas
python3 create_bsp_images.py -g ./images -b p3663-a01 -r 02 --chain B
python3 flash_bsp_images.py -P …/bootburn_t23x_py/images/642-63663-0001-001_TS2/ -b p3663-a01

After flashing:
Expected:
u32_non_gpio_select_boot_chain = 1
u32_num_boot_chains = 2
boot from chain B
Obtained:
u32_non_gpio_select_boot_chain = 0
u32_num_boot_chains = 4
boot from chain A
