LAUNCHXL-F28P65X: No output on the UART console and also unable to flash using CPU2

Part Number: LAUNCHXL-F28P65X
Other Parts Discussed in Thread: C2000WARE

Board : LAUNCHXL-F28P65X
IDE : CCS 20.4.0

We're hitting two main issues right now: Issue-1 :
We are trying to deploy basic example on LAUNCHXL-F28P65X using CCS 20.4.0. We are trying to run the example from C2000Ware_6_00_01_00\driverlib\f28p65x\examples\c28x_dual\empty_projects where have two CCS projects - one that needs to be flashed to CPU1 and one that needs to be flashed to CPU2. I want to use Flash Bank 0, Bank 1 and Banak 2 in order to flash from CPU1 and Flash Bank 3 and Flash Bank 4 to flash from CPU2. I am able to succesfully build both the projects. We are able to flash from CPU1 and generate the output on the serial console but not in the uart console(PUTTY).
For CPU2, we are not getting any logs.Putty Console :

IDE Console :

For flashing the application,we followed the below ticket.

[FAQ] LAUNCHXL-F28P65X: F28P65x: Unable to Flash using CPU2 on CCS Theia - C2000 microcontrollers f…The application runs fine immediately after flashing, but fails to start after a power cycle. How can I ensure the firmware persists in Flash memory?

Thankyou.

Hello Sai,

Since it is running fine after flashing, did you make sure it is power cycled correctly? Please refer to the power cycle sequence in device data sheet.

hello stevan

The board was power-cycled, i.e., the power supply was disconnected and then reconnected.

Please provide reference links for setting up a new project, building and flashing the firmware, and accessing serial logs via PuTTY.

hello stevan

If possible, could we arrange a quick call on Monday so that we can save time?

Hello Sai,

I am looping in relevant expert for flashing the firmware that should give you more insight.

Hello Sai,

Have you confimed if the UART settings like Baud rate and data size are consistent in your project's UART peripheral (you can check this through the .syscfg fie), your PC's UART COM Port (check this through the Device Manager) and the Serial Monitor (PUTTY)? All the 3 should have the same baud rate and other UART configurations. Can you please check this and let me know if it is consistent and correct?

Thanks,

Ira
