SCAMP: boot_aplx.s stack may overwrite boot image #137
Description
- boot_aplx.s places its stack at DTCM_TOP.
- The boot image downloaded from the host is assembled in the TOP half of DTCM.
- If the boot_image is close to 32 KiB in length then the boot_aplx.s stack may overwrite part of it.
The boot_aplx.s stack should be moved to the TOP of the bottom half of DTCM, as was done with the scamp stacks. The safety of this move needs verification because boot_aplx.s is also used to scatter load applications.
