Anyone tried a standalone CMSIS-DAP board?
Interested to know if anyone has used the schematics & firmware on from the HDK to build an mbed CMSIS-DAP board to provide drag & drop programming, serial interface and debug to a board with a bare chip like a LPC1768?
I'm thinking exactly like this attempt, but I gather he should have used a LPC11U37FBD64/501 because it needs 12KB SRAM: http://mbed.org/cookbook/lpc11u35_lpc1768_INTERFACE
Thanks,
Ian

Yeah, you can do that. I have tried to use Arch as a CMSIS DAP board. Arch uses LPC11U24 and has only 8K RAM. It works by reducing memory usage.
by remove dynamically generating MBED.HTM file, reducing some threads' stack size and optimizing code for size. The source code is on https://github.com/xiongyihui/CMSIS-DAP/tree/lpc11u24

Yep, I've built a hand held display module using parts of the HDK

posted by Ian Chilton 07 Jan 2014I replaced the ISP connector with the mbed interface from the hdk. I'll upload the schematic tomorrow which should help.
posted by Rob Cawsey 07 Jan 2014That would be great - thank you!
posted by Ian Chilton 07 Jan 2014I've uploaded the schematic.
