Need any help about tcm420p - a372374665 - 18-03-2014
This modem haven't the pinout of jtag but just have serial pinout,unfortunally, the pinout of RXD doesn't receive any command from my usb-serial adapter using putty as well as the information displayed when i turn up the modem. i test the the " RXD" that the 1.5v shown with multimeter. I am certain the connection i make is suitable. what cause this problem ?
By the way ,this modem have some "test point" beside the board eq "tp4 tp5" . will this could be the jtag pinout like "tdi tdo eq " ?
