freertos on STARF: switch context error Awaiting Agent

yingchun li

Hi, Experts
I have a board running freertos(version is V10.2.0), and the cpu
is STARF(chinese version arm cortex-m33)
Now I can connect the board, and list all the tasks, and can "display details", "display task struct" from menu, but if I used the "display Stack Frame" or "Switch context", it failed "fatel error". the message window says: "Warning: Register name cpsr unknown!".
Here is my simple scripts:
system.state
system.cpu STARF
system.JtagClock 4M
SYStem.CONFIG.DEBUGPORTTYPE SWD
system.Attach
break

perf.arm
PERF.Mode TASK

MENU.ReProgram ~~/demo/arm/kernel/freertos/freertos.men
task.config ~~/demo/arm/kernel/freertos/freertos.t32

Please give some clue, thanks a lot.
Br,
Yingchun Li

corter-m33 doesn't have CPSR register, it only has XPSR register.

Hello, To ensure a proper support of this core, I need you to send me the ELF file you are working with. In this case, please open a new ticket: "https://support.lauterbach.com/new-ticket". Best Regards,

If I force the cpu type to CORTEXM33, even if there is a warning, but seem the "context switch " works. Br, Yingchun Li
