DaVinci Mini JTAG access (Page 2 of 2)

OK, I opened the firmware (miniMaker-dump.bin) nilezon posted in Post#1 with hex editor, and find the version number is 1.0.1, so I think it will be helpful to get firmware dump of higher version. So I followed nilezon's instruction soldered J-Link EDU Mini in SWD mode to a miniMaker with firmware version 1.2.1, and I dumped the firmware like what I did for Jr., and I opened it with hex editor, and I was disappointed that the version number still shows 1.0.1.

I notice when I connect to miniMaker though SWD, the miniMaker make low noise just like when I push and hold the front LED button after reboot. So I connect to miniMaker using David's miniMover, it report firmware version 1.2.1 normally, but when I push and hold the front LED button after reboot, miniMover shows the firmware version become 1.0.1.

So I hypothesis the miniMaker can boot from two different FLASH memory, when you push and hold the front LED button after reboot or connect through SWD, machine boot from 1.0.1 firmware (bootloader maybe). Otherwise it will boot from the real firmware which is 1.2.1 in my case.

So I go to J-flasher and there is option in configuration to select from 4 different device though JTAG SWD access. So I connect to every single one of them and dumped all the flash content, the 2nd device contain firmware version 1.2.1 and all the others dumped firmware 1.0.1. I have not checked if all there firmware 1.0.1 are all the same or they are different firmware for different chips, but my guess is the MiniMaker-dump.bin nilezon posted in Post#1 is not the real/complete firmware for printer (or maybe he intend to post NFC reader flash content).

I will erase all chips and flash back the 1.2.1 firmware and test if the printer will function as normal, and then I can be sure I can go back to stock firmware.

hello, i need bump for Da Vinci mini w 1.2.3-1.2.5 firmware to SAM-BA. PLZ help because I went through this and my printer shows that it is constantly busy ..
