AM5728: Cannot connect to GP EVM

Good reference is the following wiki

http://processors.wiki.ti.com/index.php/AM572x_GP_EVM_Hardware_Setup#Powering_up_the_EVM

Here are the recommended steps to connect

- Connect the XDS200 to the GPEVM and to the host PC.

- Connect the serial port cable to the host PC

- Open a terminal and configure it to the serial port defined by the cable

- Insert the SD card into the GPEVM slot with a valid U-boot

- Plug the power jack to the GPEVM and press the S1 button to turn it on

- At the terminal, halt the u-boot procedure to keep the board powered

- Open CCS, create a target configuration file that uses the Connection as Texas Instruments XDS2xx USB Debug Probe and the Board or Device as either GPEVM_AM572X or GPEVM_AM572X_SiRevA (if using older silicon)

- With the target configuration file in focus, click on the green bug button to Launch a project less debug session

- Once at the debug session opened, highlight the Texas instruments XDS2xx USB Debug Probe/CortexA15_0 and hit Ctrl+Alt+C to connect to this core

- Go to menu Scripts and select AM572X Multicore Initialization  AM572X_Multicore_EnableAllCores

- Highlight other cores and hit Ctrl+Alt+C to connect to each of them.

o Important: the significant difference between Si Rev 1.x and Rev 2.x is the JTAG mapping of the ICSS – if you can’t connect to the PRUs, change the Device to the other Si rev.

By doing this we were able to connect to most of the cores, including the offending ARM9_ICONT1

The error message typically shows up if you don’t release the core from reset. More details on :

Mukul,

Does this need additional attention?

Yes, i will like field team from Japan to confirm that the above steps resolved their issue. Let us keep it open for another 24 hours

Biser-san, Mukul-san, All,

Thank you for your support.

I can Launch am572x, and I can connect A15 core.

But I cannot connect PUR

Could you please let me know how do I connect PRU.

I did try to chang the Device to the other Si rev.

My CCS are Version: 6.2.0.00050  and   Version: 7.4.0.00015.

Regards,

Shinji Ueda

Closing this thread as Ueda-san is still not able to get the connection up and running. We likely are still missing something in initialization steps or configuration, or there is a bad board ( I doubt that).
He is moving to a different AM437x based board for PRU dev show casing. We can reopen this thread once they have time to debug this further.
