Hello,
I am facing a weird issue on MPC5748G, 1N81M mask.
I am running attached reference_start.s file.
Depending on the content of the main (not yet called, of course) my program brick.
The program runs from ram and start.s is located at 4000_0000h.
In order to understand the root of it, I added a breakpoint at the begining of startup.s at 4000_0000h and single stepped.
The program bricks when enabling machine check.
.startup:400000EE mfmsr r6
.startup:400000F2 e_or2i r6, 0x1000
.startup:400000F6 mtmsr r6 // brick here
From there the step of the debugger stop and when I press " break " the PC is located (and stuck) at 0x10 / se_blr.
What could cause this ? I understand It could help a lot to post project/main but I can't post it publicly.
I can however email it to NXP.
Kind regards#
Hello,
I copied your startup code into my project and it works correct on my side. Could you please create case at NXP website and send me your project?
Also, please write me, which IDE and compiler you use.
