I am working on a custom board with a t2080, have previously been able to successfully connect to the processor (read SPD and perform DDR validation process).
Beginning this week I am now unable to read SPD data and/or perform the DDR validation with codewarrior. Last week I was using the usb connection, this week I have attempted both the usb and ethernet connection.
Using ccs it always seems to fail on execution of ccs::reset_to_debug (appears to succeed when using the ethernet connection, but the board does not enter debug, I can still interact with the u-boot prompt).
When it doesn't work (using the usb) the board is reset and u-boot restarts, and ccs reports the core is not responding.
I have tried just about everything I can think of and could find online, without any luck.
Currently have the TAP configured for Ethernet and it states there are no TAPs connected via USB (it is connected), but the results of source IDcore.tcl are as follow:
(bin) 49 % log v
CCS Windows Release Build 440p0
verbose logging
(bin) 50 % delete all
(bin) 51 % source IDcode.tcl
Scanning for available TAPs connected via USB.....

Test your connection using the following commands in CCS console:
log v
source IDcode.tcl
Do not forget to specify connection. Set 1 if CodeWarrior TAP USB connection is used.
You should see the similar messages:
(bin) 49 % log v
CCS Windows Release Build 469.0.0.180110-p0
verbose logging
(bin) 50 % source IDcode.tcl
