Problem Updating Firmware

[Matol]

I can't install the latest firmware on the station. I open 'firmware update' window and try both options mentioned below:

1. automatic update via direct download from github - it says that update has started and then nothing happens.
2. manual update, I download the file from github (openevse_wifi_tft_v1.bin) and upload it to the station, it shows a progress bar and it stops near the end and again nothing happens. I reboot the station and it shows old firmware version.

Current version is: openevse wifi 5.1.0_modified, latest on github: 5.1.2

Any help or pointers will be greatly appreciated

Can you try updating via the CURL method: https://openevse.stoplight.io/docs/openevse-wifi-v4/3e38d9ead39fc-user-guide#via-web-interface

Thank you for the suggestion. Unfortunately it failed and we got an "Error: 4". The update screen is attached hereto. Any pointers or ideas will be great:)

This is the same issue as here: https://github.com/OpenEVSE/openevse_esp32_firmware/issues/881 In short your options are: update manually using UART adapter or wait for official solution. The issue is probably the incorrect partition file flashed in the factory and probably all recent TFT boards are affected.

I had the same issue, I made my own uart adapter and then the bin file can be flashed easily even by web tools like https://web.esphome.io/ etc The fix on mine was complicated by a bad solder joint on the DC-DC converter capacitor which made it not functional besides the bad firmware..

Just to add more info. When get the openevse_wifi_tft_v1.bin file from github and use the 'select file' method, I can see from the developer console in another browser window:

Update Start: openevse_wifi_tft_v1.bin 1995625
Update: 0%
...
Update: 98%

That's as far as it gets.

The repartition process for the TFT LCD in the short term requires a USB => Serial adapter and esptools (requires Python and pyserial).

Download the 5.1.2 - openevse_wifi_tft_v1.bin, bootloader_16mb.bin and partitions_16mb.bin from

https://github.com/OpenEVSE/openevse_esp32_firmware/releases/tag/v5.1.2

Connect the module to the USB => Serial adapter, then put the module in bootloader mode by holding BOOT and then pressing RESET then release BOOT

Run the command:

esptool --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_size=detect 0x1000 bootloader_16mb.bin 0x8000 partitions_16mb.bin 0x10000 openevse_wifi_tft_v1.bin
