AM2634: The problem with double backup APP jump

Part Number: AM2634

Hi Team,

 

I am currently using the AM2634 chip to develop the double backup APP jump function. The two starting addresses of the double backup APP are 0x80000 and 0x200000 respectively. The programming procedures for these two addresses are the same.

When I tested the jump separately, both addresses could jump smoothly, that is, only one BOOTLOADER is configured in syscfg, and the jump to both addresses is successful.

When I configure two BOOTLOADERs in syscfg, only BOOTLOADER0 can jump successfully, but it will fail when I use BOOTLOADER1 to jump. Do I need some extra steps to jump to BOOTLOADER1? Or is there a jump example for double APP for reference?

The command when I choose to jump to different addresses is as shown in the figure below. Selecting either CONFIG_BOOTLOADER1 or CONFIG_BOOTLOADER0 means choosing a different jump address.

Kind regards,

Katherine
