Recently，I want to read and write the external FLASH on the carrier board.
HERE, I only print one variable，An “!!! Bus error” error occurred。
What could be causing this error?
Thanks very much.
As you know, the JN-AN-1217 doesn´t have implemented the read flash process.
You can look at the JN-AN-1220 and follow the external flash implementation. app_ota_client.c file
it's OK now. thank you very much for your help.
