Re: [beagleboard] After connecting CCS and JTAG to BBB and then disconnecting, the BBB hangs and doesn't show CCCC

2017-09-19 Thread John Syne 
What are you trying to do? To use CCS in bare board mode, you need an SDCard 
that sets up the board to work with CCS. From what I recall, you need more than 
just the DDR3 GEL file to get BBB working. 

Regards,
John

[beagleboard] After connecting CCS and JTAG to BBB and then disconnecting, the BBB hangs and doesn't show CCCC

2017-09-19 Thread tlsmith3777 
Running into an issue where we were able to see console output on the 
serial console when no JTAG or CCS was connected.  After connecting CCS to 
JTAG and updating the DDR3 gel file we were able to see the output over the 
CCS serial console.  After disconnecting the JTAG and CCS and doing a board 
reset, we can no longer see anything over the original serial console.  
Disconnected the serial console, did hardware reset, unplugged the BBB from 
the power supply and still the BBB simply appears hung or redirecting 
output or simply not responding CPU hung after power is applied.

What is causing this condition.  It is fine when JTAG is connected and 
using CCS. But board appears hung with no CCCs or otherwise on reboot when 
JTAG and CCS is not connected. What is taking place?
