Post by ZL1LAC » Wed Oct 16, 2019 11:40 am

Hello, I ordered the following board of bangood and need help making sure I build and compile and also get the right firmware for the following.

Code: Select all

https://www.banggood.com/USB-Communication-Duplex-MMDVM-Hotspot-Support-P25-DMR-YSF-2PCS-Antenna-For-Raspberry-Pi-p-1360474.html
Which firmware should I select to flash?

Thanks.

You really need to ask the seller that question. Hopefully they have some connection to the manufacturer and can tell you. That's a challenge with these clone boards; you never know the depth of support that is available. The listing itself is confusing; it says both:
The firmware is pre-loaded and is easily upgraded via software.
and
The firmware is pre-loaded.Please do not upgrade the firmware by yourself.

All I could find was this on the order page: STM32_HS_GPIO

The board designers page is here.

I wouldn't recommend that board to anyone no matter how cheap it is, it is incredibly finicky when it comes to beginning the flashing process, requiring that either JP1 be soldered, or that you manually set the following:

Code: Select all

BOOT0: completely removed
BOOT1: set to BOOT 1 -
and then type

Code: Select all

rpi-rw
pistar-mmdvmhshatflash hs_dual_hat
It works, but if you don't have JP1 soldered you will experience difficulty with it beginning the flash and it will require a number of tries.
If someones previous actions are any indication of their future actions, then I predict the deletion and removal of access will happen at any moment. 7-11-2020.

Once JP1 is soldered should I keep it soldered? Does it matter if I leave like that?

I have that board, but not a clone; rather the original version by Florian, DF2ET, Mathis, DB9MAT, and Andreas, DO7EN from Germany. I've never soldered any jumpers or manually set anything, and have never had any issue with using the Pi-Star script to update the firmware.

I have had unrelated issues with that board losing incoming audio with my AnyTone 878, but I've heard that may have been fixed with the latest AnyTone firmware (however, I'm waiting to install that firmware version myself until I trust that it a bit more ... there were some initial reports of trouble with it).

That is up to you. A normal person isn't going to be flashing the modem very often, but when I was working on testing custom firmwares I was flashing a modem every 5 minutes. It is incredibly annoying having to hold a pair of tweezers on the boot pads with one hand while pressing enter with the other. The other boards I've worked with I don't have to do anything, they work with no interaction. Once that pad is soldered that board works like the other boards I have and it took awhile for me to figure that out. Its always connected now, but I haven't flashed any firmwares to it in a while.

I'm just giving you my opinion of messing around with it. Performance wise I haven't had any issues with a Btech DMR-6X2.

Yeah, I've for sure got one of the clones from banggood, so maybe there is a difference. There were a few threads where people had trouble flashing similar boards too. I tried to look for those posts but couldn't find them earlier.

I have that board. Didn't need to solder anything. Jp1 was there and closed. There were some anytone issues with it receiving, but those were corrected via some settings in pi star. The receive issues were corrected via anytone firmware.

I likely got a clone board. It has performed great for me, once configured properly.
