Hi All,

I have build image using mentioned SDK for beaglebonebalck and I am getting following error -

I have tired already with pre-built image and found that the image works fine.

Pre-build image was downloaded from this link -
https://dr-download.ti.com/software-development/driver-or-library/MD-oT6mFoXgXh/0.4.2.0/cc33xx-linux-am335-img.tar.xz

Hi Sharadanand,

Thank you for reaching out! Just wanted to confirm a couple of things.

Did you edit the device tree at all before trying to build the image?
Did you partition the SD card using the script provided in the Getting Started Guide?
Are you using one of the default images or a custom image?

Best,
Corinne

Hi Corinne,

I applied patches using scripts in the cc33xx firmware,

I portioned the SD card via scripts in the bin folder in SDK.

I have used default image and I have found that the device works, I am getting above errors while I try custom image.

Warm regards,

Sharadanand

Hi Sharadanand,

Could you specify what you changed in the custom image?

Best,

I had some printks in SDIO driver side but even after reverting my changes I still see the issue.

To clarify you tried to use a default image again and the same issue occurred? When you refer to a custom image you mean that you changed the am335x image, correct? Could you clarify what you will be using the custom image for?

Lastly, could you please specifiy the exact steps you used so that I can try to reproduce the issue?

Default Image is the image I downloaded, custom image I want to use to make our custom application. I wanted to add our own kernel modules. Problem is even if I build image without any of my changes to it, I am getting above error!

Thank you for your clarification. Could you please try to reflash the sd card with using this default AM335x image (https://dr-download.ti.com/software-development/software-development-kit-sdk/MD-1BUptXj3op/08.02.00.24/tisdk-default-image-am335x-evm.wic.xz).

Once you have done that please copy the output from the install kernel command you ran previously (it should be in the directory cc33xx_rootfs) to the newly flashed sd card. If you have further issues/questions please let me know.

This has not worked as well, this image does not have show any kernel warning but does not boot up WIFI chip.

This is again a pre-build image, I need to build a custom image.,

To confirm, you are hoping to use a custom AM335x image?

Thank you very much for your patience, I think it would be beneficial to get this working again on the default image before moving to a custom image. To ensure that everything was copied over properly could you please let me know what is present in the following directories?

/lib/firmware/ti-connectivity/
/usr/share/cc33xx

Additionally what shows when you run lsmod?

Lastly, assuming that the appropriate scripts are present in /usr/share/cc33xx, could you please run "unload_cc33xx.sh" and then "sdio_rebind.sh" to see if you are able to get the module to load?

Best,
Corinne
