Program Flash via Serial


I’m working on the Digi Connect ME module. And I would like to programm the module via Serial. Is it possible ?

Actually if i want to restore a crashed module, I connect the PIN 18 to the ground, and I use a TFTPD server to download the firmware.

Could you told us what are the goals of PIN 17 18 19 20 ? On the schematics 3 of these pins are MFGO, MFGI, MFGRST, Is it possible to have more information about this ?



Look at the thread “Digi Connect ME without JTAG”. It is pin 19 (at least in my version of ConnectME) and name of the pin is MFGRST. All you have to do is to tie the pin to ground and boot -> you get a management console.
