Speed up programming

[SangSTBK]

My hex file size is 341K and it take 1 minute 10 sec to programming and 26 second to verify

I set baudrate to 230400 but it is no change

Who can help me to reduce programming time

Thanks so much

The bottleneck is probably the time it takes the device to erase and program Flash memory. JTAG would likely be faster.
