AWR2944: About second booting

Part Number: AWR2944

Hi all:

      At address 0x0, write the first sbl_qspi, point to address 0xA0000 to run appimage, when I use the serial port to upgrade online, the firmware of 0xA0000 is corrupted.
1. Will this trigger a fallback to SBL to run sbl_qspi at 0x40000?
2. If so, will the appimage at 0x200000 work if I point to the sbl_qspi at 0x40000 and point to the appimage at 0x200000?
3. until the firmware fix at 0xA0000, will the appimage at 0xA0000 still work?

    Hi,

    The fallback SBL_QSPI at 0x40000 address of flash will come into play only if the SBL at 0x0 address of flash is corrupted. If the appimage at 0xA0000 is corrupted, then you have to take care of it in your SBL implementation, the ROM will only load the SBL which is valid and handover the control to SBL.

    Regards,
