I just recently discovered that if your ISP tool (by whomever) fails at a higher baud rate it is probably because of three issues: 1. There is an error in the Philips LPC2xxx User Manual. All commands sent to the bootloader do not require a C/R and a L/F; in fact only a C/R is required. 2. If the ISP software validates all returned commands it w

I have two LPC2138 with bootloader version 2.0 and 2.12. The problem is that I apply power supply and my program doesn't not start.. the device enters automatically the programming mode. I have checked P0.14 and reset, and they are ok. One solution is to cut off power supply and wait a minute to start again. Thanks! Ezequiel ------------------------------------
