Hello,

Can any one has any utility to program the MCU flash using PC serial port.

Programming using JTAG is not a fissible solution in case of field application.

In IAP , one can erse the code & program the same if it's from keyboard....but how to program the hex file using PC serial port???

Any one has any utilty or application code which can send bin or hex file to serial port ????

Or using hyperterminal, can we send bin or hex file...

the file size may be of 16Kbyte.

Purvi,

I use HyperTerminal on Windows and minicom on Linux to do a file transfer using the xmodem protocol. My IAP code/ boot loader code executes from the secondary flash and has a xmodem client. I've written a small utility that converts the hex file to an obj file. So my xmodem client simply writes to main flash whatever it receives.

I'm not sure if this is the answer you're looking for so if you need more information, please let me know.
