From 5e9726530ff21d3bc62beaa6ac1b9437c276130a Mon Sep 17 00:00:00 2001 From: Roxy-3D Date: Sat, 15 Apr 2017 19:14:40 -0500 Subject: [PATCH] Setup to find data corruption and general clean up This data corruption problem is very difficult. Just changing the code a little bit changes whether the problem even happens and what is affected. I need these changes in the main branch so I can operate with the extra debug code always available and turned on. Everything is setup such that if M100 is turned off or DEBUG(ECHO) is turned off, the code is not affected. M100 has been made a little bit more inteligent so it can display the serial command buffers in a more meaningful way (because the data corruption seems to often times end up in that area). --- Marlin/M100_Free_Mem_Chk.cpp | 28 +++++-- Marlin/Marlin_main.cpp | 9 ++ Marlin/configuration_store.cpp | 20 +++-- Marlin/ubl_G29.cpp | 147 +++++++++++++++++---------------- 4 files changed, 118 insertions(+), 86 deletions(-) diff --git a/Marlin/M100_Free_Mem_Chk.cpp b/Marlin/M100_Free_Mem_Chk.cpp index 08236ff95..5387a71ed 100644 --- a/Marlin/M100_Free_Mem_Chk.cpp +++ b/Marlin/M100_Free_Mem_Chk.cpp @@ -41,7 +41,7 @@ * Also, there are two support functions that can be called from a developer's C code. * * uint16_t check_for_free_memory_corruption(char * const ptr); - * void M100_dump_free_memory(char *ptr, char *sp); + * void M100_dump_routine( char *title, char *start, char *end); * * Initial version by Roxy-3D */ @@ -52,7 +52,9 @@ #if ENABLED(M100_FREE_MEMORY_WATCHER) -#define TEST_BYTE ((uint8_t) 0xE5) +#define TEST_BYTE ((char) 0xE5) + +extern char command_queue[BUFSIZE][MAX_CMD_SIZE]; extern char* __brkval; extern size_t __heap_start, __heap_end, __flp; @@ -78,7 +80,7 @@ char* top_of_stack() { // Count the number of test bytes at the specified location. int16_t count_test_bytes(const uint8_t * const ptr) { for (uint16_t i = 0; i < 32000; i++) - if (ptr[i] != TEST_BYTE) + if (((char) ptr[i]) != TEST_BYTE) return i - 1; return -1; @@ -118,8 +120,20 @@ int16_t count_test_bytes(const uint8_t * const ptr) { } safe_delay(25); SERIAL_CHAR('|'); // Point out non test bytes - for (uint8_t i = 0; i < 16; i++) - SERIAL_CHAR(ptr[i] == TEST_BYTE ?
