Describe the bug

When I was changing my pages.jsonl I think I've reached the limits and then got a out of memory on reboot and loose access to filesystem editor and all web interface.

To Reproduce

Increased pages.jsonl then on boot got

Expected behavior

if there any solution to have minimal firmware or serial command to be able to get out this memory error and discards changes I made to pages.jsonl, I got lot of config and custom graphics, would love not loosing them all since I know what to change in pages.jsonl to get things back to work

Screenshots or video

There is no minimal firmware version, but you can comment out the loading of the pages.json file and compile locally.

yeah thanks that was my though and wanted to avoid, building :-), anyway, will do that thanks.
BTW as lot of boards have push button may be prevent loading pages.json when button is pressed on boot could be a great workaround, just my 2 cents :-)

[hallard]

hey just build with gitpod, awesome tool, anyway do you know the command to flash generated file (OTA or Full) without erasing FS part? Just tried to find how but did not found. Thanks

[fvanroie]

• Backup the full flash first, just to be sure!
• Flash the full binary to address 0x0 and it should preserve the filesystem if it already exists.

Backup the full flash first, just to be sure!

Thanks already done of course :-)

Flash the full binary to address 0x0 and it should preserve the filesystem if it already exists

That was the point was not sure of this one

[fvanroie]

Flash the ESP32 as normal without erasing the flash first, of course.

saved my day thanks

I let command used here as a reminder

esptool.py write_flash 0x0 sunton-8048s070c_full_16MB_v0.7.0-rc15_48884ee.bin

I also needed to add line sunton-8048s070c_16MB into platformio_override.ini because it was not into commented lines but indicated in comment (copy names from square brackets in user_setups/*/*.ini)
