I am using LPC1830, I need to download firmware with DFUSEC tool ,I confirm with FAE,
The method is :
Step 1: Change boot source pin to (P2_9, P2_8, P1_2, P1_1,) (Low, High, Low, High) for boot from USB0.
Step 2: Use DFUSEC to upgrade firmware into QSPI Flash.
Step 3: Change boot source pin to (P2_9, P2_8, P1_2, P1_1,) (Low, Low, Low, High) for boot from QSPI.
Step 4: LPC1830 will boot from QSPI and execute updated application.
I want to know if good method that I don't need to change to boot source pin for DFUSEC download ?
