flash program with jtag

Started by sperate July 11, 2006
Hello all,
I want to program my device (LPC2106) via the JTAG interface with a
homebrew software.
The problem is that i can't find any documentation on philips JTAG
programming.
I understood that many dev-kits manufacturers don't know how to
program the flash with the JTAG. They execute and debug the code in
RAM but when you want to make your card work in standalone mode you
must use the philips flash utility via the UART.
I saw that OpenOCD can do it (programming flsh via JTAG).

Can someone help me ?

Hi,
You can use JTAG to upload your software to RAM, and then call the IAP
functions to write it to flash.
