I know this sounds like an act of darin, but how about having a look at the README ? [And I really wonder why you did not find the documentation there.] > The reason I ask is that I'm trying to use > CONFIG_CFI_FLASH_USE_WEAK_ACCESSORS, but I noticed that the "md" Why would you want to do that? This is only needed in very special situations which involve a state of hardware that can be best described as broken. > command does not use the flash_readX primitives when I ask it to > display memory from a flash address. In examining do_mem_md(), I > noticed CONFIG_HAS_DATAFLASH. Did you? I don't see any CONFIG_HAS_DATAFLASH anywhere in cmd_mem.c And this is expected - the "md" command is, as the name suggests, intended for Memory Dumps. "Memory" is defined as something that can be read by just putting the address on the address bus and reading the corresponding data from the data bus, without need for any additional code or access protocols. On hardware where CONFIG_CFI_FLASH_USE_WEAK_ACCESSORS is needed, you cannot really apply the term "memory" to such a flash device - it is a storage device, but not more.
