Xip Bee Bootloader Bug

leoqian — Fri, 03 Nov 2023 08:37:25 GMT

Hello, I recently discovered an issue with BEE XIP encryption while debugging the RT1021 chip. My program structure is to write a bootloader myself (address: 0x6000000-0x60040000), and then load the APP to start (address: 0x60040000 0x6040000). The bootloader itself uses XIP BEE encryption to start, and then loads the APP and configures BEE to the APP startup area, achieving encrypted operation of both the bootloader and the App. The problem now is that even if the bootloader itself is not suitable for bee encryption, it runs normally. Once the bootloader uses bee encryption, the program will encounter inexplicable problems. Sometimes it can run normally, and sometimes modifying one or two lines of code can cause it to run away. I hope the engineers from the original factory can help analyze where the problem may be.
