SK-AM62: How to enable gpio pins

Hi Suren,

      I used TI Linux OS

Hi Suren,

i facing the issue attached the screen shot below:

Device 'Cortex M.AM64x.AM62x_SK_EVM' is not currently recognized:
- Re-run CCS installer on your existing CCS location, ensure the Product Family for your device is selected, and proceed with installation if it wasn't.
- See 'Help > Check for Updates' to check if support for this device is available through a CCS update.
- Migrate the project to closest matching supported device by adjusting project properties.
- Or contact TI for support if using experimental silicon.

i used ccs version is 12.4.00

sdk version is 08.03.00.07

which one i use tell mee.

Thanks Regards,

V Veerapandiyan

Hi Veerapandiyan,

Thanks for the screenshot.

I think it could be problem with XDS, as in the error message in console, it states XDS110 failed to connect.

Can you try installing drivers ?

Go to CCS Install Path > ccs > install_scripts

and run the following command "sudo ./install_drivers.sh"

Once done, can you confirm if the above problem is resolved or not ?

Best Regards,

Vaibhav

Hi Veerapandhiyan,

Thanks for the brief explanation of the problem you are facing.

I am going to try the same thing on my setup and see if I face the same problem.

Please give me a day time.

Vaibhav

Hi Vaibav,

 I am not understanding your replay. The screenshots are same yesterday i upload screenshot, upload your current screenshot.

Please send briefly. issue not solved. Continue same thread.

Hi Veerapandiyan,

When I said import empty example, I meant importing the empty example from MCU PLUS SDK examples directory.

To clarify more on the above please have a look at the screengrab below.

Hope this helps. You can consider this as a starting point for your custom application.

Also as you said you wanted to enable the GPIO pins, well you can do it in SysConfig itself, where you just simply need to add the GPIO module and configure the pins as output/input as desired.

Vaibhav

Hi Vaibav,

I will update monday.

Hi Veerapandiyan,

I appreciate your response.

I will look into this. Please allow me sometime to get back to you.

Vaibhav

Hi Vaibhav,

              ok. I will wait Thank you.

Thanks Regards,

Hi Veerapandiyan,

Can you please follow along the steps mentioned here ?

https://software-dl.ti.com/mcu-plus-sdk/esd/AM62X/09_00_00_19/exports/docs/api_guide_am62x/GETTING_STARTED.html

Once done, tell me about the results.

Vaibhav

Hi Vaibhav,

            I have tried but same problem is coming. how to solve the problem any ideas tell me sir

Thanks Regards,

Veerapandiyan V

Hi Vaibhav,

            Thank you for your response.

Thanks Regards,

Veerapandiyan V

Hi Veerapandiyan,

Please let me know if the steps mentioned above helped you solve your issue.

Best Regards,

Vaibhav

Hi Vaibhav,

This six steps are solved my issue.

• Click View and open target configurations tab
• Make new target configuration and select XDS 110 along with the board AM62x-SK_EVM
• Once done, test connection to the board via JTAG.
• Right click on the newly made configuration and select Launch Selected Configuration
• A bunch of cores will show up, and you need to connect to the core M4F_1
• After connecting simply load the .out file

Another one doubt, how to enable I/O expansion header and PRU header any reference documents is there.

Thanks Regards,

Veerapandiyan v

Hello Veerapandiyan,

Please go through few of the references which I am sure you will find helpful.

1. https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1255485/sk-am62-enabling-user-expansion-i-o-pins?tisearch=e2e-sitesearch&keymatch=how%2520to%2520enable%2520expansion%2520header#

2. https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1135319/faq-sk-am62-steps-to-enable-expansion-header-i2c-and-power/4214312#4214312

3. You can read about PRU here: https://www.ti.com/lit/ug/spruiv7a/spruiv7a.pdf#page=4221

The above(first two) points will be mostly talking about changes in dts/dtsi files.

But, if you were to use SysConfig and do it on MCU PLUS SDK, then you just have to configure the pin you want to use from SysConfig and the generated files will take care for the rest of the procedure.

I hope this helps.

Hi Vaibhav,
             I have enabled PRU and I/O Expansion pins all working in input and output mode.I use example uart code is not working and  i will check one led connected Tx pin is not blink data not transmit. how to write uart code.

Thanks Regards,

Veerapandiyan V.

Hello Veerapandiyan,

I would encourage you to raise a seperate e2e question for this.

Since you are talking about UART SDK Example not working at your end.

Looking forward to your e2e.

Regards,

Vaibhav

Hi Vaibhav,

I created new e2e forum for UART communication in link below:

Thanks for your support.

Hi Veerapandiyan,

Do you mean to say that you want to build the application and load the .out file onto the respective core, but all of this in release mode?

Also can you confirm if you are changing the selection in the following window ?

I reached the window by right clicking on the project in CCS and selecting Show Build Settings..

Please confirm on the above.

Best Regards,

Vaibhav

Hi Vaibhav,

1.  I check only show debug mode

2. I change Release then compile code after uploading the progrmae in same issue

any solution update.

Thanks Regards,

Veerapandiyan V.

Hi Veerapandiyan,

In CCS, when you open build settings for a particular project, by default you see that Debug [ Active ] is written.

To change it properly, you need to select Manage Configurations..

In the new window pop up, simply select Release and select the option as Set Active.

Please check the below attachment for the same.

This should work, as it worked in my case.

Best Regards,

Vaibhav

Hi Vaibhav

I changed Release mode(set active). same issue how to solve.

Thanks Regards,

Veerapandiyan V.

Hi Veerapandiyan,

After you hit Apply and close, that should be enough.

At this point your application configuration should be set to Release.

Can you please check and confirm again.

Essentially after building, you can load the .out file mentioned in the Release Directory. 

Please see the attachment below.

Regards,

Vaibhav

Hi Vaibhav,

I seeing Release folder show .out,.appimage file is there i attach the screen shot

Thanks Regards,

Veerapandiyan V.

Hi Veerapandiyan,

After building the project in Release Mode. Load the out file onto the respective core.

I just ran a simple hello world application.

Works like a charm for me.

Regards,

Vaibhav

Hi Vaibhav,

 I Understood code is working for debug mode,

Remove the power cable. the power cable insert again programme again reload then working.

Thanks Regards,

Veerapandiyan V.
