Hello, I'm working on a project using STM32F765. Everything works fine when I use Compiler V5.06. I can compile the project using V6.7 without any warnings and errors, but when I try to flash the controller I get "No algorithm found for: 2000000H - 2000008BH" I use the file system component, and this adress area is used for the file system buffers In FS_Config_MC_0.h there is
#define MC0_CACHE_ADDR 0x20000000 #define MC0_CACHE_SIZE 16 #define MC0_FAT_JOURNAL 0 #define __AT_MC0 __arm_at(MC0_CACHE_ADDR) ... /* MC0 Cache Buffer for Data and FAT Caching */ static uint32_t mc0_cache[(MC0_CACHE_SIZE+1) * 256 + MC0_FAT_JOURNAL * 128] __AT_MC0;
In the map file I see
Load Region LR$$.ARM.__AT_0x20000000 (Base: 0x20000000, Size: 0x00004400, Max: 0x00004400, ABSOLUTE, COMPRESSED[0x0000008c]) Execution Region ER$$.ARM.__AT_0x20000000 (Exec base: 0x20000000, Load base: 0x20000000, Size: 0x00004400, Max: 0x00004400, ABSOLUTE, UNINIT, COMPRESSED[0x0000008c]) Exec Addr Load Addr Size Type Attr Idx E Section Name Object 0x20000000 COMPRESSED 0x00004400 Data RW 2539 .ARM.__AT_0x20000000 fs_config.o
The compressed size (0x8C) seems to match the area that the flasher wants to flash ...0 to ..8B
I also see this in the map file
fs_config.o(.text.fs_config) refers to fs_config.o(.ARM.__AT_0x20000000) for [Anonymous Symbol]
I don't see anything like this in the map-file when I use V5 compiler.
Does anyone have an idea how to avoid this?
Thank you.
I suggest that you create an reproducer project and contact Keil support since compiler 6 toolchain is relatively new and it might still contain some glithes. This looks very unusual so there might be some configuration issue.
