Update: I was able to flash it by pulling pin 20 to ground. At least I believe that's pin 20.

Either way, I followed the image and I'm now at firmware version 1.6.1

PS: This is not my image, jut a copy of the one which was provided to me.

For my board, this didn't work. I suspect if you have a board with "jumpers", there's a definite possibility this could work. I also suspect that somebody with more knowledge of the STM32 microcontrollers and who would know how to get the proper pins in the correct state, could get my boar...

So this is where I stand. I simply can't seem to initialize the device to flash. example sudo stm32flash -v -w mmdvm_hs_dual_hat_fw.bin -g 0x0 -R -i 20,-21,21:-20,21 /dev/ttyAMA0 stm32flash 0.5 http://stm32flash.sourceforge.net/ Using Parser : Raw BINARY Interface serial_posix: 57600 8E1 GPIO sequen...

I soldered PIN 38 and 40 to each other. That didn't seem to enable the flash process to succeed. PS: The current firmware on the modem seem to identify itself as MMDVM_HS_Dual_Hat-v1.5.2 20201108 14.7456 dual ADF7021 FW CA6JAU GitID #89daa20 The board I have looks identical to the image I've attached.

I haven't had any luck yet. I can confirm that PIN 39 and PIN 40 are connected to something. Using my ohmmeter, I do see that they are in circuit. I'm not exactly certain to which part of the circuit they're connected to, but they do lead to something. Other than the pistar-modemupgrade command, is ...

I hadn't tried generic. Now I have tried it both command line and from the advanced commands.

I essentially have the same board. The one exception is that I have the surface mount antennas and the one pictured here has antenna connectors. I seem to be having the same issue. "Modem flashing failed. The serial port was either busy, or the modem is possibly locked from the vendor". I ...
