Discussion - EVE / Re: Erasing FLASH in BT815's full speed mode
« on: September 20, 2019, 10:50:59 AM »First, "CMD_FLASHDETACH → CMD_FLASHATTACH → CMD_FLASHERASE → CMD_FLASHFAST cycle" is not feasible because after flash is erasedYou're right. I fixed my post by adding an extra CMD_FLASHWRITE(unified.blob).
Secondly, at my side, with your code logic, cmd_flashread can read the flash sector correctlyIf your run the code again, what do you read? 0xFF or the older FLASH content?
after cmd_flasherase is done. The buffer is filled with 0xFF, not 0x55.
In my test I didn't switch off the board, rather I started over and sent a RST_PULSE host command before accessing the FLASH again.
