[Rpatil]

Hello ,

I am having MDEK 1001 with Raspberry 3 B+ I check all the below things

Raspberry Pi version

1. Which Raspberry hardware revision are you using? If possible please send a picture of the Raspberry with the DWM1001.
   Raspberry pi 3 B+ ( Linux raspberrypi 4.14.50-v7+ #1122 SMP Tue Jun 19 12:26:26 BST 2018 armv7l GNU/Linux)
   

   

2. Is the DWM1001 reflashed with the R2 binary?
   I am using MDEK 1001 new device

3. Which Raspberry Image are you using? The official one from the Release 2?
   Official one DRTLS_raspbian_R2.0.img

4. How do you start the DWM Daemon? Manually or just restarted the Raspberry?
   Just restarted the Raspberry

5. Can you get the system working or it keeps failing like this?
   it keep failing like this

6. Can you enter the module shell using: minicom -D /dev/serial0 (and double enter)?
   yes
   

   

7. Please send outputs of the commands on the failing system:

Hi @Rpatil
thanks for the very complete info. I wish that everybody will send info like you. It took me a while before I notice the problem. Only the RPi 3B is supported. The RPi 3B+ cannot work with the gateway because of HW change of the RPi and it cannot archive precise timings which is needed.

Cheers,
JK

Hello JK ,

Thanks for the quick reply . I have two same raspberry Pi 3B+ in one set this above mentioned problem not come its work perfectly fine . If I use the SD card of working Raspberry Pi in the other Raspberry Pi it also work so I did not recognize what is the problem with SD card ? Can you please let me know if you know from your past is SD card is also the problem source ?

Hi @Rpatil
this is beyond my RPi knowledge. But I believe that SD card wont be problem as everything runs from RAM and not from SD. Worse SD will just cause slower booting/program loading.

As it is mentioned in another thread, the 3B+ and maybe also 4 might work with gateway but with unplugged ETH cable (maybe this is what do you really observe). 3B has 100MBit ETH interface but the newer ones have 1Gbit and that floods Core with IRQs and the kernel is unable to maintain precise timing which is needed for gateway.

Cheers,
JK

Pls let me know where is the problem

[leapslabs]

Hi @Rpatil
now it looks like that the communication between the RPi and DWM1001 it not working at all. Could you check if the DWM1001 is accessible via UART?

Cheers
JK

[ 3.675891] dwm spi0.0: decode TLV failed, error 2 t:0 l:0

Hi JK ,

UART ( Tera Term ) is working if I connect DWM1001 directly to PC and able to do all the configuration like Anchor mode , Tag mode or Bridge Mode etc… even able to go to minicom but on minicom get following data

In this if I try to write si it gives garbage text . Please guide where I can doing wrong . Is it possible to make team viwer kind of session ?
Thanks in advance for your support

Hi @Rpatil
I take me a while to but Im thinking that you have a power issues. I have missed it before as I have noted that you have there 3B+ version. But after checking it all gain I have discovered this in the dmesg:

Under-voltage detected! (0x00050005)

This means that your power source is not strong enough to power the RPI incl the DEV-kit. We have noticed before that when improper power source is used then there are some issues during the communication or the dev board gets randomly rebooted. For the RPI 3B I dont even see the Power recovery message so it has to be really bad. Please use the original RPi 5.1V power source. This will also explain the weird shell output from the DWM1001-DEV.

I hope that fixing this will solve your issue.

Cheers
JK

Hello JK,

Now I have official Power Supply from Raspberry pi and in logs I didn’t see any under voltage message but still problem is there . Is this problem related with PANS which is available to download coz I reset my DWM1001 with this PANS ?

Some time minicom work some time not

even able to see anchor

Hi @Rpatil
just double checking you should have there the
DWM1001\Factory_Firmware_Image\DWM1001_PANS_R2.0.hex

Could you access the shell directly form the RPi?

Best regards,
Jiri

Hi Jiri,

Yes we are using the same PANS screen shot attached

Some time we are able to communicate with shell through Raspberry pi ( minicom ) screen shot attached but most of the time get garbage text

Hi @Rpatil
well I almost fires all my advice’s - we have correct RPi & power supply & image. Lets focus on your last note about the garbage text - this could be a clue. If the SPI is not working and you are reading garbage text via RPi uart then it could mean that the signal gets disrupted by noise. I have checked again all pictures and I think that the flat cable could be an issue. I have never used it before and I didnt expect it that it could be an issue but it is possible. Remove the cable and replace it with following header:

you need 2x13 positions.

The cable you have there has some parasitic capacitance between wires (especially the long cables) and it can corrupt the data transfers.

Cheers
