My S7G2-SK development board is resisting all attempts to enter Serial Boot Mode. A RX62N board works every time.
I have the board powered with a USB power cable on J19. R107 to R110 removed to isolate on-board JLink.
J1 has pins 2-3 linked. A reset is applied via J2 after power is applied.
Using RFP V3.04.00 and a USB connection to the PC is made via J5, the board enters USB Boot Mode.
Taking note of earlier related post I have and external RS232 drive connected to P109 and P110. USB to PC connector removed.
Applying a reset via J2 after power and sending nulls at 9600 baud there is no response from the S7.
Is there some critical detail that I have missed?
Regards
David
