Pretty sure my Anan-10 hates me. I've been trying to troubleshoot why the SWR meter in Thetis gives completely wild readings like 63:1 or 17:1 on transmit while my LP-100A says things are perfectly fine. I get these readings whether I'm using 10 watts or 2 watts out. Logically, the equipment is set ...

I would like to do some forensics on it. Maybe I could revive it.

Shoot me an email at my qrz.com email and we'll talk.

I hate Internet threads that never have a conclusion so here it is. I sent the 10E board to Doug, W5WC, who found that both the flash rom chip and the FPGA were bad. He didn't think it would be cost effective to replace them so I opted to purchase an Anan 10 board that he had on hand. What I did to ...

Thanks, Rick I'll check that out.

I do have a nice scope but it's only two channels. It can do I2C/SPI, UART/RS232, and CAN/LIN but I can't say I've ever used any of those capabilities.

I wonder if U1 could be programmed with a CH341?

With D2 & D7 REMOVED from circuit:

U1 Pin voltage:

1 - 3.3
2 - 3.3
3 - 3.3
4 - 0
5 - 1.44
6 - .02
7 - 3.3
8 - 3.3

Those don't seem right to me. Voltages remain the same with or without J12 in place.

Same error as always.

BTW, both diodes test good.

I'll try pulling D2 & D7 and try flash again.

U1, according to Digikey, is obsolete. Not sure if there is a substitute or not. I don't have any of these parts on hand in any case.

I've tried a second USB cable from the blaster with the same results. U1 Voltages are identical with J12 jumper in place or removed. Pin: 1 - .18 2 - 3.1 3 - 3.3 4 - 0 5 - 1.08 6 - .02 7 - 3.3 8 - 3.3 With blaster attached and running, voltages above also remain the same. https://mm.digikey.com/Volu...

If U1, the M25P16VMW6G flash serial chip was bad, would we expect this sort of error?

Yes I did.

Does a document exist anywhere that shows correct pin voltages, waveforms, etc?

I just tired re-flashing the board again. Same result.

Here's the setup:







I note that D10-D19 are NOT blinking.

I think I must have damaged one or more of the board components somehow.

Guys: Thanks to Rick specifying the FPGA part numbers it seems that the Anan-10 that was sold to me as a "none-E" actually is an E. That's a bit annoying. I guess I'll have to assume that the guy that sold it to me didn't know, either. ...maybe. :| Anan10E_FPGA.jpg I do have an older versi...

Thanks for the reply, Scott. Yes, I used your article when I attempted the upgrade. But to answer your question, none of the bootloader utilities are able to detect the radio any longer. Doesn't matter whether I use a piece of CAT5 connected directly from the computer Ethernet port to radio, or atta...

I’m going to try and summarize what has been a long, frustrating process. I got a new-to-me Anan-10 last week (not the E). According to Thetis it was running firmware 1.5 and working perfectly well. I, apparently foolishly, decided to try and upgrade it to protocol 2 firmware the very first day I go...
