does anybody know how I could speed up the download to targetsystem using uVision2? The highest baud rate is 57600. Higher baudrates are impossible because I am using 4MHz on target system. I would buy hardware to add into the pc if I could find anything. But I haven't found anything until now. Thank you for your help Bye ...Leo
Using special frequency for CPU clock should allow a C166 family microcontroller's UART support higher baud rates. For instance, if you used 3.6864 MHz instead of 4 MHz you would be able to work at 115.2 kbps. Regards, Mike
Are you sure you're sending data at the maximum throughput; do you have a fast serial card, with deep FIFOs enabled, etc? A previous client had a fixed download "speed" of 57k6; they used old 486s with Win3.1 and it took ~20 minutes. One day I tried my 433MHz Win98 Celeron laptop - the baud rate had to stay the same, but the download time reduced to ~12 minutes!
