Hi

 

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 ?

 

Thanks

Ken
