Unable to open Web Server on T-Beam v1.1

[Shropshire]

Hi, I've just bought a couple of T-Beam v1.1s and updated the software from GIT using Visual Code/PlatformIO. All looks good on the OLED..... BUT.. I'm unable to connect to the on board web server (192.168.4.1) - it seems to say Connection Rejected.

Thanks in advance,
Tony

[rvt]

do you upload the filesystem?

example:
pio run --target uploadfs -e psRam

[maks]

@rvt would you have some more details about the need to upload a filesystem?

I tried to just follow the instructions in the wiki https://github.com/gereic/GXAirCom/wiki/Flashing-the-Software-with-a-PC-(Windows) though I'm on Linux and so used the flashall.sh shell script. It all seemed to work using the esptool and my TTGO Tbeam v1.2 seems to boot ok, though I do see some errors logged on the usb uart and I'm able to connect to the Wifi AP, but as soon as I try to the web server on 192.168.4.1 I see in the uart logging that it crashes and resets which seems same as the original report in this issue.

I flashed firmware_v5.4.0_psRam.bin with matching spiffs_v5.4.0.bin and the other binaries used flash_all.bash so I'm not sure what I'm doing wrong?

In case it helps here is the log, its for 5.3.4 since I tried it in case it was any better than the latest version but pretty much same behaviour:

It look like you haven't flashed the spiffs
[I][main.cpp:1857] setup(): SPIFFS total=113201 used=0 free=113201

[maks]

@gereic thank you for having a look at this and thanks for making such a great project!

I flashed using esptool on linux multiple time now with different versions of the binaries.
I tried again now on the latest published version with:

esptool -p /dev/ttyACM0 -b 921000 write_flash --flash_mode=dio 0x1000 bootloader_dio_40m.bin 0x8000 partitions.bin 0xe000 boot_app0.bin 0x10000 firmware_v5.4.0_psRam.bin 0x3d0000 spiffs_v5.4.0.bin

so I'm not sure with the spiffs why its not there? is 0x3d0000 the correct address for the filesystem? I just got that address from the flash_all bash script and its the same value as in the wiki.

I also just realised that I got my board from a vendor instead of from the "official" Lilygo store on Aliexpress, so I've ordered another unit from them just in case the vendor I bought from has sent me a dodgy unit.

[maks]

sorry I should have also included the output from running esptool which seems to show the spiffs binary being written correctly to flash?

hi again @gereic I just had a look a the code in main.cpp around line 1828 and it looks like you have changed the code recently and now have code that will format it on opening:

 // Make sure we can read the file system
  if( !SPIFFS.begin(true)){
  //if( !SPIFFS.begin(false)){
    log_e("Error mounting SPIFFS");
    //while(1);
  }
  log_i("SPIFFS total=%d used=%d free=%d",SPIFFS.totalBytes(),SPIFFS.usedBytes(),SPIFFS.totalBytes()-SPIFFS.usedBytes());

so I would expect that by calling SPIFFS.begin(true) with the bool set to true it will format the spiffs when its opened, so it would be expected to be empty.

Should I instead go back to using an older version of the code which still uses spiffs?

[maks]

oh! I just saw you pushed up a commit with newly rebuilt 5.4.0 binaries, so I flashed with them and now I'm able to connect successfully to the http server!
I'm not sure what specific change in one of the commits since the previous 5.4.0 bins fixed it, but very happy its working for me now on my board, thanks again @gereic !
