LPC4357-EVB: unable to program

Former Member
Former Member over 11 years ago

I have programmed my software into LPC4357-EVB board and it became totally unusable - can't use JTAG at all.

I suspect that PLL1 initialisation was incorrect so the micro simply locks up.

 

The question is: How can I reprogram the board?

According to NXP spec, in order to get access to ISP I need to use USART0 or USART3.

 

However, on this board USART0 is hardwired to RAM and USART3 is connected to USB power protection chip.

 

Is it possible to reprogram the board without hardware modifications apart from soldering UART TX/RX pins?

    Are we looking at the same board?
