Hi all,

I want to perform memory test (FLASH) during U-boot and read the results after the operating system (Linux) is booted up. Is it possible? If so, can anyone guide me to do so?

On which plattform do you want to try this?

You can activate CONFIG_LOGBUFFER in your board config file, and try it, grep for "CONFIG_LOGBUFFER" for examples. The enbw_cmc is a good example for an arm plattform, but you need also adaptions in your Linux kernel, as this is not supported in mainline kernel! See here a try to bring it into mainline

But this patch does not longer works for newer kernels, as logbuffer handling had changed ... so maybe, you have to do a complete rework ...
