Hi Vaibhav, Thanks for your reply, sorry there is a misunderstanding for you, when customer took the picture of the EVM they did not change the bootmode yet, and when they start the testing, actually they did set the bootmode according to our guide below. And to double confirm it, customer could see the "CCCCCCC" output in the UART terminal, which means the bootmode setting should be correct. Customer mentioned this EVM has been used by their colleague before, so we doubt that the OSPI flash is not empty, and maybe we need erase it. May I know do we have some reference guide about how to erase the OSPI flash? Thanks, Kevin
