2日 ago Commented Hello, Thank you for reaching out to us! At the first look, it seems that the .textf section is not allocated (or is incorrectly allocated) in the linker script. In order to be able to help you, please provide the following: - toolchain and e2 Studio version used - compile/link options - linker script - map file - the full project or a minimally-reproducible example (if possible) If you wish to share the file(s) privately, please open up a support ticket and attach them there. Please let us know if we can be of further assistance. __ Best regards, The Open Source Tools Team

7月 18, 2024 Commented Hello, Please consider the following: test.c: #include int main() { int x = 12; __builtin_rx_brk(); x = 13; assert(x == 12); return 0; } The commands below illustrate both approaches: rx-elf-gcc -msim test.c -g rx-elf-gdb a.out -ex "target sim" -ex "load" -ex "br abort" -ex "run" -ex "bt" -ex "c" -ex "bt" Explanation: After creating the executable from the source file, we launch a debug session and insert a breakpoint into the abort() function. When we begin execution, the debugger will first stop at the BRK instruction. If we issue the continue command, the debugger stops at the abort() breakpoint. In both cases, the program state can be inspected: in our example we display the call stack. Please elaborate further if this behavior is not what you are looking for. __ Best regards, The Open Source Tools Team

7月 2, 2024 Commented Hello, Thank you for reaching out to us! Unfortunately we are not able to reproduce the issue. In order to aid our investigation, please attach the full-built e2 Studio project for both of the mentioned cases. You may also share the code privately with us by opening a dedicated support ticket, where you can attach it. __ Best regards, The Open Source Tools Team

6月 11, 2024 Commented Hello, Indeed, these options are useful when developers write the time critical functions in assembly, having the assurance that the reserved registers won't be allocated in other parts of the application. Avoiding fast_interrupt functions written in C, either by using normal interrupts or by writing them in assembly, should keep the mint-registers unmodified. Please let us know if we can be of further assistance. __ Best regards, The Open Source Tools Team

6月 11, 2024 Commented Hello, A fix was included regarding this issue in the GCC for Renesas RX 8.3.0.202405 release. When using -mint-register=2 -msmall-data-limit=512, RX 8.3.0.202405 produces the following instructions: Source code: #include "iodefines.h" unsigned char Buffer[32]; unsigned char* pHead; unsigned char* pTail; volatile unsigned char Data; void ServiceFastRXI1(void) __attribute__ ((fast_interrupt,optimize("-O2"))); void ServiceFastRXI1(void) { *pHead++ = SCI1.RDR; *pTail++ = Data++; if(&Buffer[32] == pHead) { pTail = pHead = &Buffer[0]; } ICU.IER[15].BIT.IEN6 = 1; return; } void main(void) { int i; pTail = pHead = &Buffer[0]; i = (int)&ServiceFastRXI1; return; } Compiled output: .file "test.c" .section P,"ax" .comm _Buffer,32,1 .comm _pHead,4,4 .comm _pTail,4,4 .comm _Data,1,1 .global _ServiceFastRXI1 .type _ServiceFastRXI1, @function _ServiceFastRXI1: ; Note: Fast Interrupt Handler pushm r1-r5 mov.L #_pHead, r5 mov.L [r5], r3 mov.L #_Data, r1 mov.L #_pTail, r4 add #1, r3, r2 mov.L r2, [r5] mov.L #0x8a020, r2 mov.B 5[r2], r2 mov.B r2, [r3] mov.B [r1], r2 mov.L [r4], r3 add #1, r2, r13 add #1, r3, r12 mov.B r13, [r1] mov.L r12, [r4] mov.B r2, [r3] mov.L [r5], r3 cmp #_Buffer+32, r3 beq .L5 mov.L #0x87000, r5 bset #6, 527[r5].B popm r1-r5 rtfi .L5: mov.L #_Buffer, [r5] mov.L #_Buffer, [r4] mov.L #0x87000, r5 bset #6, 527[r5].B popm r1-r5 rtfi .size _ServiceFastRXI1, .-_ServiceFastRXI1 .global _main .type _main, @function _main: push.l r10 add #-4, r0, r10 mov.L r10, r0 mov.L #_pHead, r5 mov.L #_Buffer, [r5] mov.L #_pHead, r5 mov.L [r5], r4 mov.L #_pTail, r5 mov.L r4, [r5] mov.L #_ServiceFastRXI1, [r10] nop rtsd #8, r10-r10 .size _main, .-_main .ident "GCC: (GCC_Build_8c9e6e87e) 8.3.0.202405-GNURX 20190222" Due to mint-registers being set to 2, GCC is free to use/allocate/trash r13 and r12 in the fast interrupt function, without saving and restoring them. Due to msmall-data-limit > 0, GCC will not allocate r11 anywhere. If you encountered a different behavior, please let us know. Best regards, The Open Source Tools Team

5月 16, 2024 Commented Hello, Thank you for reaching out to us! We are sorry for the late response and are glad that you have found the solution. Unfortunately we are offering support for toolchains only, FreeRTOS usage is outside of our domain. We recommend seeking help at https://community.renesas.com, if you encounter any other, not toolchain specific issues. For toolchain questions we remain at your disposal. __ Best regards, The Open Source Tools Team
