You need to include hardware_exception as one of your link libraries.Okay I see
I'm getting an error just adding a headerCode:
fatal error: hardware/exception.h: No such file or directory 11 | #include "hardware/exception.h"
I think you can simplify stack_guard to:As far as the assemble code goes I'm out of my depth there, the comment explain what is going on but I'm not that versed enough to understand how to change it.
Code:
void __attribute__((used,naked)) stack_trap(void) {asm volatile( " push {r0-r3} \n\t" // Save R0-R3 on original stack " mov r0, sp \n\t" // Get stack pointer " adr r1, 2f \n\t" // Address of data block " push {r4-r7} \n\t" // Save R4-R7 " mov r4, r8 \n\t" // Copy R8-R11 to R4-R7 " mov r5, r9 \n\t" " mov r6, r10 \n\t" " mov r7, r11 \n\t" " push {r4-r7} \n\t" // Save R8-R11 " mov r4, r12 \n\t" // Copy R12 to R4 " mov r5, lr \n\t" // Copy LR to R5 " push {r4-r5} \n\t" // Save them " ldm r0!, {r4-r7} \n\t" // Retrieve R0-R3 from original stack " push {r4-r7} \n\t" // Save them on the new stack " ldm r0!, {r4-r7} \n\t" // Retrieve R0-R3 from exception frame " push {r4-r7} \n\t" // Save them on the new stack " ldm r0!, {r4-r7} \n\t" // Retrieve R12, LR, PC & PSP from exception frame " push {r0,r4-r7} \n\t" // Save Original SP, R12, LR, PC & PSP to stack " mov r0, sp \n\t" // R0 = Location of saved data " ldm r1!, {r2-r4} \n\t" // Load next three words from data block " mov r5, #0 \n\t" // Create dummy exception frame " push {r2-r3} \n\t" // PC = stack_report, PSP = Thread mode, Thumb " push {r5} \n\t" // LR = 0 " push {r5} \n\t" // R12 = 0 " push {r5} \n\t" // R3 = 0 " push {r5} \n\t" // R2 = 0 " push {r5} \n\t" // R1 = 0 " push {r0} \n\t" // R0 = 0 " bx r4 \n\t" // Exception return: Thread mode, main stack " .align 2 \n\t" "2: .word crash_report \n\t" // Address of crash_report routine " .word 0x1000000 \n\t" // PSP = Thread mode, Thumb " .word 0xFFFFFFF9 \n\t" // Exception return: Thread mode, main stack ); } Statistics: Posted by Memotech Bill — Tue Jan 14, 2025 7:50 pm
