Description

This task adds support for the IAR Embedded Workbench for Arm toolchain for the twincpu feature branch on Cypress psoc6.

Specific issues addressed:

  • Added type casts to (void *) and (char *) here and there
  • Added "0" initializers in a few structs with empty "{}"
  • Changed a few Image$$ references to make use of the REGION_DECLARE macro
  • Added dummy elements to arrays to avoid zero length arrays.
  • Added #pragma required to avoid link errors for IAR
  • Added struct tfm_pool_chunk_s_t to avoid compilation errors for zero sized array
  • Removed return with value from void function, the return value was not used anyway
  • Added psa_call_dummy() for naked assembly function that would require stack
  • Added rule to generate IAR secure link script
  • Added cmake files for IAR
  • Updated existing cmake files to allow IARARM
  • Added startup and linker scripts
  • Added cy_syslib_iar.c
  • Added build instructions for IAR

Hi Thomas, tfm-twin-cpu is a dedicated project tag for multi-core feature development with special schedule, task plan and target, which have been determined.
Please select other tags. Sorry for any inconvenience.

Yes, I just noticed.

I had planned to integrate my working psoc6 changes yesterday, but I was two commits behind and when I updated to the latest , it would no longer run due to linkage changes.

Trying to keep up with this is like herding cats ;) You are always behind :)

Yeah, we have been such a quick pace for a while. There are still some major PSoC 6 feature coming in next 2 weeks. So I guess there will be a more stable code base in mid-OCt.
