SC20 Linux Unpacking Tool(emmc_writer) not working

I got a build for SC20 in Yocto Linux and i followed the steps of “Quectel_SC20_Linux_Packaging&Download_On_Ubuntu_Guide_V1.3.pdf” to write the image. Although i did everything in the documentation, i could not write the image. Im getting this error :

  • Mini USB to USB cable plugged.

After executing 2.1, check if there are any files in the Quectel_Emmc directory, as long as these files are generated, you don’t need to worry about them.
The operations 4 and 5 are performed on the QFIL software, not in the Linux environment or Ubuntu, first ensure that you are in the emergency download mode (port 9008)
