program external device through SWD

03 Sep 2012

is it possible to flash program a external device through SWD using the MBED?

do you want to program. a custom PCB using the normal method for flashing MBED???

I guess it would be possible but you will need to remove. the LPC1768 from MBED PCB :-(

and some ninja soldering!

to connect to your PCB.

but you can make MBED a serial interface so you can use flash magic. or similar

as always the more info you supply more responses :-)

No, i just want to use SWD to program an external uC.

Thats what i need, got some examples somewhere?

Thnx!

search MBED for prototype to hardware...

one of the threads has a ln implementation of programming LPC1768 using MBED, as serial adaptor.

but basically it is USB serial to TTL (3.3Volt)

I think there is a stock program for this in the handbook!

but if I get a chance next weekend I intend to publish a programmer solution for bair metal chips :-)

but I do have some more work to do to complete it.

cheers

Sounds great, but is that the SWD interface? or a uart connected interface? I really need the SWD interface.

my bad! USART Solution

do you have a link to SWD?

so I can investigate.

I thought. it was a cheap J -TAG
