Hi,

I am struggling to get a working connection to the UART0 on the LS1.

I managed to get UART1 (mapped to port /dev/ttyMSM0) working after browsing through this forum, and luckily found this post: https://developer.qualcomm.com/forum/qdn-forums/hardware/qualcomm-roboti.... Without it, I wouldn't have known to turn the DIP switch to OFF.

I have tried to set up a similar connection to UART0, but mapped to /dev/ttyHS1 (I've also tried /dev/ttyHS0), but with no luck.

So, my question is, are there any magic tricks like the DIP switch for UART1 to get UART0 working? Would appreciate some documentation regarding this.
