Hello there folks,
I am trying to find information on booting from UART and thought it should be relatively straight forward. Set boot mode pins to '11', tell the efuses the boot src is UART1, make sure the GPIO Bt Sel is set to IIM, not GPIO.
Then when the imx25 comes out of reset it would initialise the UART to 115,200 etc and wait for the data on usb or UART and boot from the first detected, and which point I would send the application via a terminal program to the imx25.
However, reading the ref manual (chap 7) seems to suggest that there is a specific 'serial downloader protocol', information for which I cannot find.
Can anyone point me in he right direction?
Many thanks in advance
