Because some driver only support jetpack4.6, I need downgrade jetpack5.1 to jetpack4.6.
I use sd card image to install, but Xavier can’t work and show error message.
message is "Pres ESC in 5 seconds to skip startup.nsh or any other key to contunue. Shell> "
We have mentioned at this instruction that QSPI image needs to be updated.
I don’t know why it’s working on your case.
The only suggestion I can give is to flash your device with SDK manager via JetPack.
Sometimes QSPI can automatically upgrade, but it has no ability to downgrade. I wouldn’t trust automatic upgrades anyway (I recommend flashing QSPI always upon change of release unless OTA update did the job).
