- This is the second part of my attempt to solve a probem from which i suffer since a long time that I was not able to solve it to this date
- Here is the first part:
https://forum.pine64.org/showthread.php?tid=18788
- I am a Linux beginner but this problem makes me really suffer.
- This was one of the reasons to buy a Pinephone
- and that is create files on the external SD card of my Pinephone
- and process it further on my Ubuntu PC.
- I created with Abiword a file on the external SD card of my Pinephone
- Then I sticked the SD card with a card reader into my Ubuntu PC
- There I was able to open and modify the Abiword file.
- But when I wanted to save the file under the same name it was created on the Pinephone, I had no permission to do this.
- I suppose to solve this problem I have to create on my Pinephone a file everybody has the permission to modify
- How can I do this?

Hi everyone,
I am trying to run meshtasticd on my Pinephone.
Suddenly tough, the received bytes of the SX1262 are all zero, and I never managed to get the standard 0xA2 answer back.
I2C communication works still, which is why I am suspecting that the radio chip is at fault.
Does anybody know what I was doing wrong or how to debug this?
Onto the details, I simply implemented an SPI device driver which translates to I2C such that mestasticd can communicate with it as if the ATTiny bridge isn't there.
The code for the kernel driver and a dmesg trace with debug output can be found here: https://gist.github.com/pectec/ffddf32ae...041bc92bbe
Any help on this is appreciated
Thank you,
Nick
Edit: I managed to damage it, Pine64 says that there isn't going to be a production batch anytime soon.
My only option is DIY at this point (using a [url=https://www.amazon.de/dp/B0CSFG65MS?psc=1&ref=ppx_yo2ov_dt_b_product_details][/url]Waveshare RP2040), which I'll do when I come around to it, so I'll mark this issue as solved.
