Part Number: MSP432P4111
Tool/software: TI C/C++ Compiler
Good morning,
We are developing some code and every time we initiate an I2C communication the program gets stuck here:
ti_sysbios_family_arm_m3_Hwi_excHandlerAsm__I:
.asmfunc
tst lr, #4 ; context on PSP?
ite NE
mrsne r0, psp ; if yes, then use PSP
moveq r0, sp ; else use MSP
mov sp, r0 ; use this stack
stmfd sp!, {r4-r11} ; save r4-r11 while we're at it
mov r0, sp ; pass sp to exception handler
mov r1, lr ; pass lr too
mov r4, lr ; preserve LR in r4
ldr r2, excHandlerAddr
blx r2
mov r0, sp ; for ROV
mov r1, r4 ; for ROV
$1
b $1 ; spin here indefinitely
Do you have any idea why?
Thank you.
