Timed out while waiting for ack

Nobby · December 22, 2024, 12:34pm

Hi all,

Just like Hophi, i tried to read the flash of my Toniebox, without success.

I tried this with differrent USB to UART converters.
The cheap China converter that I use for my ESP8266, a CP2103 evaluation board, and a FTDI cable.
The FTDI cable doesn’t have a DTR pin, I think I have to use the RTS pin, right?

I use the 10 pin adapter cable from Aliexpress to connect to the C3200’s debug port.
I use Windows 10, Python 3.8.1, PIP 24.3.1

d:\TonieBox\revvoxx\cc3200tool\cc3200tool>cc3200tool -p COM4 --reset dtr read_all_files ExtractedFromBox/
2024-12-22 13:03:58,099 -- Connecting to target...
2024-12-22 13:04:00,415 -- timed out while waiting for ack
2024-12-22 13:04:02,633 -- timed out while waiting for ack
2024-12-22 13:04:04,853 -- timed out while waiting for ack
2024-12-22 13:04:07,070 -- timed out while waiting for ack
2024-12-22 13:04:09,275 -- timed out while waiting for ack
2024-12-22 13:04:09,276 -- Could not connect to target: Did not get ACK on break condition

So used my LogicAnalyzer to see what happens.
First without a Toniebox connected.
What I do not understand:
TXD from the PC only goes to low level for 192ms.
I would have expected some kind of data (a request or so).
Or is only the change from high to low the request, and the C3200 should start to send some data?

I also tried this with the Toniebox connected:

There is no reaction from C3200.
What I also do not understand, why is the RXD signal (Toniebox’ TXD) always low?
I would have expected it to be high when idle.

Regards,
Nobby

Please give us more details. How you wired everything etc.

Might be a stupid question but this is what held me up for a loooong time: do you provide additional power to the box? I didn’t and I had basically the same problem. As soon as I connected the battery to the board after connecting the board to the UART, everything went quite smooth.

Nobby · December 22, 2024, 8:17pm

Here is a drawing of my wiring:

Does this help?

Has anyone before used a logic analyzer to log the communication between PC and Toniebox?
I hoped that comparison between good case and my case could give some hints what I am doing wrong…

The Toniebox board is only connected to the speaker, but not to the ears.

Nobby · December 22, 2024, 8:21pm

I guess I have already tried every combination of power supply.
Both, battery and charger.
Only battery.
Only charger.

But I will try again:

Connect UART to Toniebox
Connect battery (but not charger) to the Toniebox
Start communication:
cc3200tool -p COM4 --reset dtr read_all_files ExtractedFromBox/

Nothing change

I know my cabling is quite long, especially for 921600 bit/s.
The FTI cable is around 150cm, the pcb clip from Aliexpress is 24cm, my breadboard wires between FTDI cable and pcb clip are 10cm…
That’s why I already tried with the CP2103 board to save the 150cm of wires.

But since I don’t see any data being sent from PC to Toniebox, I’m not sure if this is really a wiring problem, or a software problem…

I also beeped the Aliexpress PCB clip, every connection was OK.
I even used the LogicAnalyzer at the pcb clip pins. With cc3200tool I saw the same as shown above.
When sending test data with a terminal program, I saw the expected data.

If I read your image correctly then you don’t have dtr? Why are you using —reset dtr then?

Nobby · December 23, 2024, 10:42am

Thank you Henry,
I think that was the hint that I needed.
I thought that RTS and DTR were just different names for the same things, but it seems they are not…
I could have seen in the LogicAnalyzer log, that the C3200’s RST was held low all the time, I think that’s why RXD was also low all the time!

So I manually held the RST line to GND when connecting power (only charger, not battery, that’s easier for me with only two hands).
Then I released RST and executed
cc3200tool -p COM4 read_all_files ExtractedFromBox/
Then communication looks like this:

At the end I get “One or more files could not be verified or read at all”
but that’s much better than before and might be due to the very long wires.

I will now try to make the wires as short as possible and then try again.

This is totally fine in most cases. Please always post the full log. Be sure you got the full flash based backup!

Nobby · December 25, 2024, 8:10pm

I read the data three times and compared the content.
It was everytime completely the same, expect. that the first dear contained the file
sys/date_time.cfg
and the others didn’t.

Here is the log:

So it seems that reading data was OK.
But to be sure to do not brick the Toniebox when writing I used the CP2103 evaluation board as USB to UART converter. This alowed me to reduce wire length to around 30cm. And the board has a dedicated DTR pin.
With this board i executed
cc3200tool -p COM5 --reset dtr read_all_files targetdir/ read_flash backup.bin
and compared the read data again.
That data is the same again.
So I’m quite sure now that I can read and write without problems.

To summarize my problems, I think I made two mistakes:

I connected the FTDI’s RTS pin to the Toniebox’s RST pin because I thought it did the same as a DTR pin. But it didin’t. It held the Toniebox all the time in reset state.
The CP2103 board even has separate RTS and DTR connectors.
When I tried reading without “–reset dtr” I didn’t handle the RST manualy because I thought it is enough to connect SOP2 to VCC.
But it was necessary to connect RST to GND when powering up the Toniebox.
When the Toniebox had started, I disconnected RST from GND.
With correct handling of RST I had no problems to communicate with the Toniebox.

This looks fine to me. You got all certs, so the flash can be always rebuilt manually.
Be sure you also got the flash based backup too!

Nobby · December 25, 2024, 8:40pm

OK, that’s fine
What do you mean with “flash based backup too!” ?

Just make sure that your single file backup.bin is not empty (0 KB) but 4MB in size.

If it is empty, try to read it again with this command:

cc3200tool -p COM5 --reset dtr read_flash backup.bin

Had the same issue with reset connected to RTS. The reset did not trigger that way if using --reset dtr. However, found out that --reset rts is also valid and works.
