Hello,
I am trying to developp BAF (Boot Assist Flash) programming for factory programming of our gateway.
At the moment I am using MPC5748G LCEVB.
I have experience with previous BAM , over can bus.This is my first BAF attempt.
In case of MPC5748G it seems BAF only works with serial communication over PB0 / PB1.
I connected my FTDI_RX to PB0_LIN0TX and FTDI_TX to PB1_LIN0RX.
Whole PFLASH is erased. ( FF value as seen on debugger ) so there is no valid boot header anywhere.
BAF area is programmed ( content that was delivered with the board ), attached.
As LCEVB xtal is 40 mhz, I have set up the baudrate to 48 000 baud as indicated in the reference manual, 8 data bit, no parity bit, 1 stop bit.
I am sending \h(FE ED FA CE CA FE BE) over FTDI , I checked on the logic analyser : the message is sent at 48 000 baud.
No response is received.
Any help appreciated.
Kind regards
