[WEB Installer] Lolin C3 mini loads but does't boot wled

[marcobrianza]

Hello, just tested the web installer with release 0.14.2 on Lolin C3 mini The installer does its thing but the board does not boot wled afterwards. The serial writes these messages:

E (286) esp_core_dump_flash: No core dump partition found! Ada E (4856) phy_init: load_cal_data_from_nvs_handle: calibration data MAC check failed: expected 68:b6:b3:75:79:60, found a0:76:4e:43:be:70

FYI tasmota web installer works correctly on this board

New C3 bootloader has been added to web installer. Try it out and report.

Hello, just tested and resulted a different error

As I do not use web installer (and have no knowledge of its workings) I cannot help any further. Please post any log files of the flashing process if you can find them. Perhaps @Aircoookie will find the time to look into this issue but you are welcome to help and debug too.

P.S. Do not forget that S2, S3 and C3 are still in experimental phase and not all corners have been ironed out.

Just a quick note that might help in finding the solution: Loading the latest firmware from platform.io works and the code runs but I get similar message as the previous bootoader:

E (286) esp_core_dump_flash: No core dump partition found! Ada

(no problem with the calibration)

If i understand correctly, the bootloader offset for the C3 is 0x1000, partition 0x8000 and firmware 0x10000 https://docs.espressif.com/projects/esp-idf/en/v4.3/esp32c3/security/secure-boot-bootloader-size.html ATM it adds the bootloader on 0x0 i will change that and will ping you once you can try it on a seperate fork

@marcobrianza https://lost-hope.github.io/WLED-WebInstaller changed it for 0.14.2. please try

Hello, the new repo has the same error, BUT 0.14.1 WORKS!

There is still this message at boot: _E (286) esp_core_dumpflash: No core dump partition found! Ada but is the same with the platform.io upload so I guess is not a matter of the web installer.

I have noted that the first time I use the web installer in a new board there is this message _E (4980) phy_init: load_cal_data_from_nvs_handle: calibration data MAC check failed: expected a0:76:4e:1b:ed:2c, found a0:76:4e:43:be:7_0__

at following flashes of the same board this Disappears.

I am not sure how serious is this issue, but at least I checked that the default mac address of the baord is not overwritten because when the software load the mac address of WLED-AP is the correct one.

So I would use the method used for 0.14.1 because at least the board loads WLED that looks functional to me

There is still this message at boot: _E (286) esp_core_dumpflash: No core dump partition found! Ada but is the same with the platform.io upload so I guess is not a matter of the web installer.

If you want to play and get rid of the message, there are partition maps in the tools folder. Adjust and upload from PIO.

ok that was both really value able info, cause for 0.14.2 there was a bootloader change and an addition of the partion table. both removed/reverted now for 0.14.2 on my fork, so please try again

[marcobrianza]

yes this works, with the same boot message _E (286) esp_core_dumpflash: No core dump partition found! Ada

Please close the issue if it is resolved.
