I'd like to experiment programming the mbed's LPC1768 dev board (https://os.mbed.com/platforms/mbed-LPC1768/) using ISP with FlashMagic.

Is this possible without requiring physical modification of the board?

  • \$\begingroup\$ Why exactly do you want to use that particular software? Typical MBED boards support a CMSIS-DAP interface (which your software along with many more mainstream choices supports) but it is unclear if that particular very old board does. Perhaps you should stick with the built in programming method for that board and moved to an SWD solution when you go to a production prototype. There are also other LPC1768 boards which expose the necessary signals you could try in the meantime to verify assumptions. \$\endgroup\$ – Chris Stratton Mar 7 at 18:05
  • \$\begingroup\$ @ChrisStratton, could you suggest other such boards? I've struggled to find many still in production \$\endgroup\$ – 19172281 Mar 7 at 18:11
  • \$\begingroup\$ Maybe the real question then is why you want to use such an old MCU for your project. Interestingly, in a quick search one cheap source of LPC1768 boards seems to be knock-off 3d printer controllers implementing smoothieware.org/flashing-the-bootloader \$\endgroup\$ – Chris Stratton Mar 7 at 18:15
  • \$\begingroup\$ @ChrisStratton, I didn't think the LPC1768 was particularly old. I'd think it'll be around for a while? \$\endgroup\$ – 19172281 Mar 7 at 18:36
  • \$\begingroup\$ The chip may not be discontinued soon, but you did notice that development boards for it seem to be. It's about a decade old in a field that has seen a lot of growth - much of the explosion of the Cortex-M parts into popularity has happened since. \$\endgroup\$ – Chris Stratton Mar 7 at 18:42
