I've already discussed this with Andy personally, but I figured I'd post it here, too, to see if there was any interest. With the existing ISP-ICP bridge solution you need to move jumpers on the MCB900 to switch between programming the bridge MCU and programming the target MCU. If there were an option to strobe DTR to cycle power to the bridge MCU without strobing RTS/RXD to toggle the bridge MCU reset, you could program the target MCU without having to shunt the bridge MCU power or open it's reset line (i.e. you could leave the jumper in the same position used to program the MCU on the MCB900). This may or may not be of much practical use on the MCB900, but we have a production test fixture with an integrated ISP-ICP bridge MCU (basically a copy of MCB900) and it would be great to be able change between updating the firmware in the bridge MCU (or even program it the first time) and programming target MCUs without having to do anything to the hardware.

Feature Requests / Support for P89LPC9381
November 17, 2008, 12:12:38 PM
This is supposedly just a P89LPC938 with half of the flash removed and several of the peripherals removed (CCU, EEPROM, XDATA ram, etc.) to reduce cost. I haven't been able to get any information yet from my FAE regarding the device ID / Signature, but I just asked. If there's anything I can do to help, let me know. It would be awesome if the program were user-extensible to add devices via some sort of device definition file, but as long as your willing to keep up your awesome level of device support, I guess that's not necessary!

LPC9xx/LPC9xxx / ICP w/ LPC9381 and FDI USB-ICP
November 17, 2008, 12:07:36 PM
Hi Everyone,
Has anyone had any success with ICP on the P89LPC9381? I am using the USB-ICP programming adaptor and a custom PCB with the P89LPC9381 on it. Neither UCB-ICP nor FlashMagic seem to "officially" support the P89LPC9381, but an NXP FAE told me that I should be able to just treat it as an P89LPC938 with half of the flash blocks and a few less peripherals, since that's basically what it is. I tried this, though, will no success. FlashMagic complained that the ID bytes didn't match (which is to be expected, since it's not *actually* a '938), but erased the device anyway with apparent success. When I attempted to read the device signature manually, it returned all 0s.
Any ideas?
