Hi
Plans to meshtatic to use ? Or some experimental test?
Thanks
There is a variant for the Wio-E5 from Seeed Studio in the firmware, but its filesystem is not yet working. That device has a STM32WLE5JC module, so I guess it wouldn’t be too hard to port it to a STM32WL55 once it is fully working.
Nice!!!
No, it will not hard to port i once is fully working.

Is that DEBUG right ? and freeze the UART to send commands ?
This is the same as what we currently get using the Wio-E5.
It seems to be missing the values from the filesystem, e.g. Radio myRegion->freqStart -> myRegion->freqEnd: -> ( mhz) should display the real frequency range.
Do you have any experience with filesystems on embedded devices? We have at least this clue:
.pio/libdeps/wio-e5/littlefs/lfs.c:1224:error: Corrupted dir pair at {0x0, 0x1}
Currently LittleFS is implemented on emulated EEPROM on flash, but it’s only 2kB in size.
Hi, do you mean that frequency is stored in FS ?
This is the why that I’m getting blank…?
A member on stm32wl55 micropython lora lib solved the FS format this processor…
They can format on stm32wl55
I tested and works
Do you want the link of GitHub discussion ?
Sorry, not experience on FS
I hope that helps…talk with Angus
Yes, indeed the region is stored in the FS, and from that it derives the frequency range.
That GitHub discussion is about using MicroPython, so I’m afraid it won’t help much for C++.
But source code em C++, right ?
The source code of Meshtastic is in C++ indeed.
In my second boot, i can see my configs

may you send your boot sequence ?
Sure, here it is (from a while ago using firmware version 2.1.13):

exactly equal to me!
please, after the first reset, make again the reset and send the boot log again…
After reset it indeed finds the configs, but it cannot read them (e.g. it’s missing the frequency values in the logs) and halts afterwards:

exactly this happens on my STM32Wl55 and freeze…
team, is it possible make tests using static data config? (not storing in FS)
