I am working on SIM7600EI 4G LTE Modem and modems firmware version is LE11B12SIM7600M22.
Recently I was working on SD Card file system of Modem and I was able to work with “C” directory which is a default directory, I also wrote the data in the directory and read the data from the directory but when I was trying to change my directory to other directory like “D”, “E”, “F” the modem was not responding at all. I am unable to figure out why this is happening its not even giving error.
I will really appreciate any suggestion on this.
Following is the test log
