I have implemented a Segger Open Flashloader and I have a 2MB (0x200000) external flash mapped to base address 0x00000000. In jlink, when I do a savebin f.bin 0x00000000, 0x200000, I have found that it won't read more than 1MB. I have implemented the SEGGER_OPEN_Read() function. After I was getting this error, I did a test by doing the read function as follows: int SEGGER_OPEN_Read( U32 Addr, U32 NumBytes, U8 * pDestBuff ) { return NumBytes; } Now I still get exactly the same error.

I'm implementing an open loader (actually I had it working on the ST-Link debugger but that sw has bugs) and I'm using IAR EWARM. I see the wiki page for the open loader specifies that all the code should be in a section called PrgCode and all program data should be in a section called PrgData. I have all my Init() functions and friends implemented and my struct FlashDevice filled out etc. I'm getting an error when loading the openloader in jlink "****** Error: Error while loading flash algo ELF…
