I am using sl8082t modem with frescale’s IMX6 solo processor in our custom board.
If i turn on the modem , the entire board reboots after some time.
After restarting the board for 4 to 5 attempts reboot is not happening.
Also the reboot occurs only if the SIM card is present.
If the modem is not turned on, or if the SIM card is removed, I am not facing any reboot issues.
As far I have analysed the board gets rebooted on any one of this situation.
=> 30 to 40 seconds after power-on-sequence is passed to the modem.
=> If I attempt to transfer any file to FTP server.
=> If I make a call more than 2 to 3 times.
=> If I send a message ( rare occasions)
Please Guide me solve these issue.
