#161450 - Me too Responding to: ???'s previous message |
I did one with the Atmel AT89C51RB2. This chip has the possibility to set a boot vector to the boot loader.
But the NXP doesn't. Once the first Flash pages are erased and for some reason it resets (e.g. Power failure), the device is gone. And it does not resolve the problem with starting the user code after power on. The first load will be by a parallel programmer. Flash Magic would not work due to the RS485 hardware. Stefan |
