Hello Everyone,
I am working on i.MX7D based custom platform with secure boot enabled. We use u-boot as bootloader which is flashed on NAND. I see that u-boot is also stored in a secondary NAND area (secondary bootstream) when flashed using "kobs-ng" utility. Based on this, I have following questions:
If during primary image read there is a page with a number of errors higher than ECC can
correct, the boot ROM will turn on PERSIST_SECONDARY_BOOT bit and perform
SW reset (After SW reset, secondary image is used).
Thanks,
Vishal
Hello,
generally the secondary boot option is intended to be controlled by boot ROM
automatically without special customer's activity (to perform the secondary boot
directly). Note, usually applications cannot cause ECC error in software. ECC
relates to hardware errors.
Have a great day,
Yuri
