Cannot Update Controller!
« on: December 10, 2019, 15:24:45 »
Just built me controller (V4.6) using all Farnell parts aprt from the PCB and Micro-controllers which were purchased pre-programmed.  when I fired up the Astro EQ config utility it informed I had out of date firmware so I used the utility to update it.  The update attempt failed and I get a message stating "Programmer not responding" and "Not in sync".  I have attached a picture of my controller to aid in diagnosis, any help would be appreciated.

Could you post a picture of the back on the PCB.
Did you connect +12V first before the USB connector?

Its odd that there have been three of you now in quick succession with similar issues, so trying to get to the bottom of it.

I've just checked a few of the current batch of ICs and they seem to be working fine in my board, so while its conceivable there's a bad few, its unlikely.

Thanks for the quick response, yes I'll double check the back of the board with a magnifying glass and when I've done it post a picture here tomorrow.

Hello Again,
I have checked the board for dry joints and reflowed 3 but to no avail. Attached are two pictures, the solder side of the PCB and a screen script of the failed update prcess.  Hopefully they will be useful to you!  Thanks & Regards

Can't see anythign visibly wrong with the board, other than one end of R14 isn't soldered, but that wouldn't cause an issue as it is just the power LED.

I'll post out another ATMega to you tomorrow. It will be interesting to know if it is a faulty chip.

Kind Regards,
Tom.

Could you check C13 and C14 first, there appears to be a solder short between them which would stop the crystal oscillating.

Sorted out the duff joint betweenC13 & C14 and away she goes, loaded the EQ5 config to the controller successfully.  My mount is actually a GPDX but I believe the gear ratios are the same.  Thanks for the help I shall now sort out the stepper motor cables and mounting gear.  Regards
