Other Parts Discussed in Thread: UNIFLASH
Good afternoon,
I'm designing a board with the main bootmode as a QSPI and the backup as USB. In the TRM I see how to set USB as the backup via a pull down resistor on pin 15 of the bootmode pins. Where can I find more information on booting through the back USB when the main mode is already configured for QSPI? I did not find information related to back boot configuration in the TRM, this is what I am seeking.
Additionally, is it possible to boot from JTAG as a backup? I did not see this listed as an option. I am trying to cover the first time use case where the NVM connected to the QSPI does not contain valid data.
Thank you!
