Hi all,

Ive hit a bit of a road block building elements.

Ive finished the power section and main processor and am currently in the flashing stage. I cannot get ST Programmer to connect to the MCU. Ive reflowed the MCU and checked all the power pins on both the MCU and JTAG which are all sitting around 3.3v as expected. Likewise nothing untoward in the power section.

Ive also checked the ST link is working with a previous braids build which connects up no problem - for reference I'm using a genuine ST Link V2 and STM32CubeProgrammer on Mac OS both Catalina and Mojave.

Any help or tips for things to check would be greatly appreciated.

Thanks in advance!
FYI - Managed to fix it :hihi:

Feel free to delete post or keep if it helps others.

SOLUTION: Updated ST Link firmware on a windows system as it wouldn't update on Mac OS. MCU connects now all good :yay: :tu:

It still won't connect on Mac OS but seems to work through windows.

Thank you ! and thanks to Forestcavera one more time !

how could i measure the output with multimeter ? i need special cable to plug the MM to the ring and tip ?
You can use alligator clips and a regular patch cable coming from the module, or if you can get creative with your multimeter probes you can do that too. Then you measure the voltage coming out of the cable.

Hi!

After some succesfull Mutable builts I am trying to flash my DIY Edges with my st link avr adapter (the one on the left) but I cant manage to detect the board.

Can you please confirm that I am using the right device?

I used the left for Grids and other similar and the right for modules like performer, clouds or braids.

thanks in advance

Make sure that programmer supports PDI, most clones dont and edges uses an Xmega which requires PDI programming

Hi! Thanks for the response. The chip is ATXMega32A4U, so it seems to be that PDI thing.
I use AVR dudes, os ok to use it?

Thanks

OK thanks almost done
Does a MM with 3x 0 will be ok ? (ie 5000 and not 50000)
I have issue with the measure of Y output : it still at - 4.xx v and bias button have no effect.

3x will get you close, but it is recommended you have a much higher precision multimeter to get it working like a factory module, ideally 50,000 count, or higher.

You may have an issue there, it's been a while since I did my builds but I don't recall having any issues on the Y output. Check your soldering.

AVRdude isnt the issue, the programmer is. You need one that supports PDI, I use the AtmelCE

Ok thanks a lot. Do someone know any cheaper clone that works? I will only use it once.
I have an USBASP that i think does not support PDI.

Hi. I've build clouds, but have problems with flashing software to MCU. I've compiled 2 binaries for bootloader and main software, following tutorial from github and flashed MCU with FTDI adapter. After that nothing happened. No light from LEDs, no reaction to buttons. I've checked soldering many times and asked friend, to make simple programm, that flashes onboard LEDs and it was working fine. Can i somehow check if my compiled binaries correct? Or there is some special way to flash MCU? Is JTMS wire needed for flashing?(stlink v2.1 don'thave it, i think) I have FTDI adapter and STLINK V2.1 on nucleo board, but it is my first time encounter with digital things.

Hi so marble is working perfectly, i just put the led backward :bang: and tried to desolder them but i think i have ruined the pad !
Now its backward and not working.
Does i have ruined all the board ?? how could i repair that !? :bang:

You could try to fix a delaminated pad by very carefully exposing some of the copper in the trace and soldering a jumper wire to it, but it's never going to be pretty... If the copper is still connected throughout (just not attached to the board) you can solder to it, but it'll be rather fragile.

I saw copper ring when i push out the LED. I take a pad from another board ?
Could i directly link the leg with a wire to the trace or resistor ?

There are a number of ways that this can be fixed. One is removing pads from another board or using wires to rewire the parts.

Personally I'd rewire it using 30 ga wire wrap wire between parts. Remove any bad traces or copper that could short things out and then add the 30 ga.

Also go to YouTube and look for something that would work for you. There's a number on PCB repair, just find one that makes sense to you.

Hi,
Just finished a jakplugg nRings, it flashed and turns on properly, LEDs all work etc.
Only problem is the output is SUPER quiet, I have to really boost the output to hear it and there's a lot of noise/hiss.
What I can hear sounds fine and it seems to all be responding correctly.

Any ideas what could be causing this or where to check first?

I've already reflowed the STM and the WM8731 but not saying there may not still be a problem there.

Thanks!

It's more likely a poor connection somewhere in the audio path (or a mistake in a gain resistor value).

Building a 1u Shayshez Apex (peaks clone) right now and I am a little bit baffled. When I try to connect it to the stm utility software using a genuine st-link it never connects. It does turn on and every measurable voltage checks out, yet no LEDs light up (maybe only after programming it? no way to tell). I ordered the ST32F103CBT6 from lcsc.com as this was the only place still having them in stock. Seems to be a reputable seller, so I don't think I received a fake. Anyone has any guesses where the problem may lie?

Hi all,

Ive been building an Elements and I fudged the MCU. Ive got a spare MCU and board on the way (although wanted to keep this for a 2nd build).

On removing the MCU I accidentally lifted a pad. However, looking at the eagle file it doesn't look as if that leg of the MCU actually goes anywhere. Ive got two options.

1. Migrate some of the expensive parts from board 1 to the new board and go from there or...
2. Carry on with the board ignoring the lifted trace and put a new MCU on.

I'd prefer option 2 but I'm not sure if its feasible given the lifted pad.

Any help greatly appreciated.

Thanks in advance!

Sure, option 2 should work & will save you from having to re-do the entire board. Just make sure you don't short the pin, without a pad underneath the solder will want to go elsewhere. (if it's not used it may not even cause harm in case of a short but better not risk it)

Awesome I’ll just stick another MCU on then. Thanks mate!

Got an interesting issue with a pair of Veils 2020 builds, interesting because it's consistent across both modules.
Both channels 1 and 3 output 2.7v with the gain up and nothing patched in. Channels 2 and 4 respond as they should.
Here are a few photos, though the flash doesn't lend itself to the full pcb photo:

Silly question but you are powering via the ribbon cable?
Have you tried pluging the ST-link the other way round?
The module will do nothing until the firmware is flashed, bootloader first.

Which 2164 are you using ? (if you are using SSI2164 you may well need changing the RC values at the input - check the datasheet!) Try with an as2164 or v2164 if you are using ssi2164s.... :-)

Ahh...really.
Thanks, I'll check it now. Would it only effect channels 1 and 3 and not all of them?

I just checked the data sheet and it states:
"The SSI2164 is quite tolerant of RC network selection, but
220Ω/1200pF has been proven to work well over a wide range of RIN values; existing SSM/V2164 positions with RC networks of 500Ω/560pF
also work well for RIN of 20kΩ or greater."
Veils 2020 uses 510r/560pF with Rin at 49.9k.
