Cyclic reset with SIM presence

Hi everybody!

For a training period, I’m working on a Q2406B. It works fine alone, but when I plug a SIM on the development kit, a cyclic reset appears every 5 ou 6 secs… The problem is that I can’t find where the problem comes from, it’s very disapointing! :confused:
I looked for every fonctions of reset, wartchdog, etc… but nothing. So I tried to find a new firmware to upgrade the Q24, but there’s nothing on the wavecom site wich seems to be a firmware…

So, I don’t know what to do… I’m lost!!! :cry: :cry:

Could someone help me please??

Thanx,
