Building FW

[toyotahead]

My setup:

• RPI 3B
• Pi-Star:4.1.7 / Dashboard: 2024010 (clean and fresh install)
• ZUM Radio-MMDVM for Pi v1.0 (HRO white PCB) (presently has as purchased FW: MMDVM:20190130)
• 64GB new SD card (full size confirmed with df -h)
• Utilizing ethernet cable not wifi
• SSH'd into the pi via Putty
• instructions: https://www.hamradio.com/images_managed/misc/H0-016486_MMDVM_Pi_1_User_Manual_1_2020.pdf (in the pi-star sections)

Goal:
Update FW to enable FM & M17 modes

I have done this procedure in the past with a different board without issue. However this time I am being hung up at the compiling stage. I am able to get to the "make pi-f722" where it fails with:

It doesn't seem to matter what is uncommented, these define error follows the first line that is uncommented.

What have I missed doing to progress this compiling process?

You have removed the # from in-front of all of the define statements, this is part of the statement and NOT a comment!
They should be '#define xxxxx'

Thank you Phil

Not sure if it is relevant but, I forgot to mention this MMDVM board is bran new. It has never been used before.

So I am not quite sure why the instruction says to "uncomment" certain lines as the default Config.h looks like you are suggesting. Perhaps I just didn't understand....

"#define xxxxx' (minus the single quotes)

If I am to understand you correctly I just need to put back all the # and then run the 'make pi-f722' command and all these feature will be enabled by default? To which I have tried and indeed I now have files populated in my /bin folder. YA!!! (hopefully the features are enabled :) )

I continued with the instructions into the flashing section. Everything seems fine right up to where it begins to flash where errors are encountered (see below) and the mmdvm board seems to lock up with a solid red PTT, and solid orange PWR led lights only. (no rapid flashing STAT anymore). A power cycle resolves this and both the pi and the mmdvm start up as per normal with its old firmware 20190130

The specific command within the flashing script file that seems to fail looks like: sudo stm32flash -v -w mmdvm_f7.bin -g 0x0 -R -c /dev/ttyAMA0
I have read somewhere it is the -c switch that causes problems but I am hesitant to just try removing it without seeking assurance I am on the right track. Are you able to advise further?

73 Thanks again!

sad news... tried with the -c removed. Flash appeared to work as it was reporting "Wrote and verified 100%" but upon reboot only the power led is illuminated and no flashing STAT led. Upon checking pi-star dashboard no modem is recognized / attached.

Thinking the fw didn't flash I ran the same exact procedure again. Once again I see the PTT led illuminate and the fw begins and reports "Wrote and verified 100%". Once complete the PTT led extinguishes leaving only the PWR led on.

Rebooted

Same result, only the PWR led is on and no modem detected. I assume the flash did not work / corrupted the fw on the chip. But it seems as though that the chip is still present and responding as the ptt led going on and off.

Also if I put the -c back into the flashing command I get the previous flashing error as I did before "Failed to read ACK byte" and the PTT and PWR leds are illuminated.

What is the path forward from here? Really hope this board isn't junk at this point :/
