Hi,
I've recently encountered some problems with J-Link VCOM using higher baudrates. The custom board I use needs 1250000 baud which is rather unusual but nevertheless, another ordinary USB/Serial converter seems to not have any problems with it. Every time I'm trying to open the connection using specified baudrate(1250000) J-Link disconnects from Windows' device manager. It happens no matter what serial terminal I'm using(tested on Putty, SmarTTY, TeraTerm, and so on). I wonder if there are any hardware-related constraints to J-Link's max baudrate (from my understanding they shouldn't exist as the USB CDC class doesn't have such) or maybe it can be fixed via a simple software update? Using lower baudrates(115200, etc.) works without any problems.
JLink EDU
Serial number: 260108435
Version: 10.1
It has the newest available firmware installed.
Any help would be much appreciated.
Regards,
Mateusz Piesta
