Speeding up Bootloader
I've tried to speed up the download rate of Bootloader.The code size is ~ 100k It currently takes 3:30 to download the firmware, yielding an effective baud rate of 4000! What can I modify to speed up this process?
Below are my calculations and findings:
download time vs. baud rate setting Baud Rate download time 9600 5:51 19200 4:37 38400 3:35 57600 3:34 115200 3:30 230400 3:30(as you can see, a baud rate setting of 38400 and higher is NOT a limiting factor here) code size: 104906 bytes effective baud rate: (104906 bytes * 8 bits/byte)/(210 seconds) => 3996 baud
