We have confirmed the operation on our original board that
"STM32MP151CAA3" mounted on.
When I start our Cortex-A7 (Linux) FW and try to load our Cortex-M4 (RTOS: uC3) FW , an error message is output on the console of Linux.
The steps when an error occurs is described below.
Is there any possible cause for the error?
1) Write our Cortex-A7 (Linux) FW to a SD card and start it with our original board.
2) Build our Cortex-M4 (RTOS: uC3) FW. ⇒ Build is successful.
3) Transfer our Cortex-M4 (RTOS: uC3) FW to our original board by scp.
4) Start our Cortex-M4 (RTOS: uC3) FW by Cortex-A7 (Linux) FW.
⇒ Linux console shows the error message.
Hi @HMasu.1 ,
Did you check your M4 firmware runs ok in Engineering mode ?
Hi @Community member ,
Thank you for your reply.
I have checked in Engineering mode by using MDK Arm (uVision).
Loading M4 firmware is successful, but if I started program by step-in, suddenly the debugger disconnects when RTOS starts.
uVision don't show any message.
And I cannot get fault reports from uVision because the debugger disconnects.
