Hi,

Unfortunately I’m having the same issue with the Linux One-click FW upgrade as in HL7812 firmware upgrade fails immediately on linux - #2 by jerdung, i.e. the process fails before any actual connection to HL7845. Please find the log file attached. No *dl.log file was generated.

I’m running Ubuntu 20.04.6 LTS with the following steps:

  1. Give access rights to /dev/ttyUSB0 (UART1)
  2. Test that AT command interface is working fine.
  3. Try to install mono-runtime. Unfortunately no mono-runtime installer can be found from Sierra Source.
  4. Install mono-complete following the instructions from Download - Stable | Mono
  5. Verify that installation was successful by entering mono --version
  6. Try to run the one-click FW file by entering SFXTERM=0 DL_PORT=ttyUSB0 DL_BAUD=3000000 ./HL7845.5.4.10.0

My guess is that the problem is that there is no ~/mono-runtime folder due to different procedure on installing mono. It would be great if the file mono-runtime-x86_64-installer mentioned in the FW upgrade instructions could be made available. Or optionally, I would be grateful for some instructions on how to configure mono to be compatible with HL7845.5.4.10.0. I have to admit that I’m a complete newbie with mono.

Thanks,
Olli
