 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Hi Peter, Any love for this? POKE HARDFAULT Allows generating a HARDFAULT from code to allow testing of startup/recover. MM_Misc.c void cmd_poke(void) ... ... } else if((p=checkstring(cmdline, (unsigned char *)"HARDFAULT"))){ //int *harderror = NULL; *harderror = 10; // Generate hard error //*(volatile uint32_t*)0x10000 = 1; //BUS errror asm volatile (".word 0xf7f0a000\n"); //Undefined instruction } else { getargs(&cmdline, 5, (unsigned char *)","); if ((p = checkstring(argv[0], (unsigned char *)"BYTE"))) ...

Easy to add, but what does this do that CPU RESTART doesn't? |

It triggers the HARDFAULT_EXCEPTION handler, I was thinking along the lines of testing an embedded setup recovers from an unknown future glitch by putting the POKE HARDFAULT command in the code during testing. > cpu restart > poke hardfault Error: Invalid address - resetting > Seemed like a good idea at the time. Maybe wait to see if any seconders for the idea. Edited 2025-10-10 17:54 by disco4now F4 H7FotSF4xGT |

So where would you find that on a normal boot to BASIC computer? Maybe a Commodore 64 could do it but it would need an extremely obscure POKE and it's wasn't a "normal" computer anyway because Commodore BASIC didn't support it's hardware. ;) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

It's a bug I have introduced when drawing circles with thick edges without an interior fill colour - will fix Edited 2025-10-10 18:36 by matherp |
