anyone can access the BB C3 with serial cable, serial or usb ?
I suggest you read the Sytem Reference Manual. There are no problems accessing the serial port on the Rev C3 Beagle. You must have the correct ribbon cable and a null modem cable to make it work. There is a section on the SRM that takes you through step by step to make sure you have the correct cable configuration.
yes … at the time that I seguindos the step does not give any error but does not arrive in time …
