Hello,
Greetings!!
I have purchased the TMDSCNCD2800157 evaluation board for testing purpose.
I am facing the issue in Flashing the code from JTAG interface.
Following observations I have seen in the board:
1. All power supply are okay (Checked in DSO).
2. LED 3:A is not glowing.
3. CCS studio is not able to detect the JTAG connection (Test connection option is there in CCS Menu).
Please provide your valuable suggestion to resolve the issue.
Kind Regards,
Jainam
the user guide linked above should give the required settings for standalone or "boot from flash" mode.
make sure that S4 is correctly set:
Finally depending on the setting of S1:A and S2:A you may lose the abilty to connect through JTAG. S1:A affects the UART channels, S2:A affects TDI and TDO.
Regards,
Cody
Hello Cody,
Please find the switch position for f2800157 eval board.
| Switch | 1 | 2 |
| S1:A | ON | ON |
| S2:A | DOWN | |
| S1 | DOWN | DOWN |
| S3 | UP | |
| S4 | UP | UP |
| S5 | DOWN | DOWN |
During test connection (In CCS), this error message we are getting,
Regards,
If S2:A is down you must configure your target configuration to use CJTAG mode. 
Regards,
Cody
