Reply-To: ham...@googlegroups.com

My repurposed Grape-DRF has become unoperational due to an apparent Raspberry Pi failure.

Initial symptom was inability to upload a data set even though connected to the server. Subsequent symptoms were USB enumeration errors, failure to connect to disk drive and failure to connect to SD card.

After multiple attempts to recover using the DRF troubleshooting protocol without success, I’m pretty confident that the RPi is faulty (and likewise the SD card).

This system functioned flawlessly for the three weeks since receiving it, so I’m disappointed that it’s now out of service.

After testing all other components appear to be operational - what are my options?

Thanks,

Al -W0TBR

Update and request for guidance.

After a long wait, RPi finally opened without an OS but was able to install RPi Desktop onto a 64Mb USB thumb drive. Boot up VERY slow as is response to desktop apps. Makes me skeptical of a full recovery but might give it a try.

Need help confirming next steps:

- since Ubuntu OS not present, will need to download/install (from Desktop?) - or is Ubuntu OS included in Grape-DRF image?

- once Ubuntu OS installed, will need to burn Grape-DRF image to uSD card;

- insert uSD card into RPi and start full Grape-DRF system (hoping that RPi recognizes and loads card despite damage to slot);

- name primary user “ubuntu” in Ubuntu OS;

- copy runGrape software into Documents directory;

- modify settings in configuration file to match personal PSWS settings;

- save and restart system and watch for successful launch or note errors for diagnosis and possible solution (or deep six RPi?)

Does the above make sense and in proper sequence?

Any and all guidance welcome as collective learning experience!

Al,

Given what you've said about the original card being "stuck" in the

connector, it might also be that the connector is screwed up to the

point that no card will ever work in it again.

You might be better off to simply replace the RPi altogether- that

could well be the path of least resistance and fairly low cost.

Thanks - but tried that but card was stuck and wouldn’t release normally - had to use needle nose to get it out.

Ran a diagnostics on the card and it was a FAIL so have new uSD card on the way and I’ll try to download the image, burn it to the card and see what happens!

Update to come in a couple of days…

If you haven't already done so, try pushing the SD card IN so that the mechanism will release the card and eject it.

Tnx, Graham - I’ll try a new uSD card, but seems the old one is stuck or jammed in so I’ll have to investigate further…

It may not be that the Raspberry Pi itself has developed some issues, it may be that the SD card has failed

My first step would be to get a good quality SD card i.e. brand name like Sandisk and of a type known as "Application Performance type 2" i.e A2

https://www.nextorage.net/en/supportpage/card-about-app-performance-class/

A bit pricer perhaps but better suited to the task of Raspberry Pi usage.

Hi Al,

If you have another computer with a uSD/USB slot, all you have to do is burn the Grape1-DRF image to the uSD card, then boot that card in the RPI and update the uploader.config file station info: token_value, node, grid, thestationid, instrumented.

Then hit ctrl-C in the terminal window if it is running the scheduler, open a new terminal window and enter:
python3 gnuradio_schedule.py
It should start running. LMK

73,
Bill AB1XB

Correction…

Then hit ctrl-C in the terminal window if it is running the scheduler, open a new terminal window and enter:

cd Documents/runGrape
python3 gnuradio_schedule.py
