- Subject: [ECOS] Thumb/exceptions in program
I know very little about ecos, but:
Interrupts in the ARM processor all run in 32-bit mode - so you will hit
problems if you try to run interrupts in Thumb mode.
As the remainder of the code works OK in 32-bit mode, the other possible
explanation of a sata abort of not having set up the interrupt stacks cannot
be correct.
