Title: LPC2138 DK
Post by: alex_k on October 23, 2006, 12:56:35 pm
Hi,

I'm using the IAR development kit for the LPC2138, and I'm having some problems programming the flash. Flash Magic cannot seem to connect to the processor.

P0_14 is asserted low, and reset is controlled by DTR on the UART.

Every single time I try to read or program the flash, I get the error

"Failed to read the device signature"

Cheers,

Alex

Are you controlling P0.14 using RTS? If not then I've never tried mixing how P0.14 and RST are controlled. Either I've used switches for both or I've used the UART signals for both.
