?Hi Tommy,
Are you working with the SK-AM62B or the Beaglebone Black?
If you are using the beaglebone black, then you should find the dtb file in cc33xx/cc33xx_rootfs/boot directory. Did you run the install_kernel command?
Hi Sabeeh
Yes, I have already executed make install_kernel
.
By the way I am working with "SK-AM62B",Is there any difference?
Thanks
Hi Tommy,
I think you are executing the wrong command. We have build script available, please follow directions here where you can use './build_cc33xx.sh' script:
And yes, for SK-AM62B we have prebuilt images available so that it is not necessary to build the SDK. Simply flash the image below to an SD card:
You can find all the images here:
Hi Sabeeh
I don't have an SD card; I am using the eMMC DFU method for flashing.
Anyway :
1.I have some concerns regarding the device tree file after applying this patch. Currently, the system I am compiling is using a 64-bit device tree, so it will not be included in the build.
My device tree file is located at:./board-support/ti-linux-kernel-6.1.80+gitAUTOINC+2e423244f8-ti/arch/arm64/boot/dts/ti
The patch device tree file is located at:./board-support/ti-linux-kernel-6.1.80+gitAUTOINC+2e423244f8-ti/arch/arm/boot/dts/am335x-boneblack-cc33xx-boosterpack.dts
"
2.Also, how should I flash and load the firmware?"
Best regards

Hi Tommy,
Yes you will not see am335x (arm) DTS file because you are compiling for am62x (arm64). You need to manually apply am62 patch to your tree. You can do this with command:
"patch -p0 < <path_to_cc33xx_folder>/patches/cc33xx_am625-sk_dts.patch"
I suggest following instructions on how to build from Am62x guide. Find link here: https://dev.ti.com/tirex/explore/node?node=A__ACjr-X897enaTGByTlD6Pg__CC33XX-LINUX-MPU__lBDUdCJ__LATEST
Hi Sabeeh
Where can I find the GPIO numbers and functions related to WiFi for the AM62x?
Thanks
Hi Tommy,
In the 'cc33xx_am625-sk_dts.patch' I mentioned above you can find example devicetree that should describe the pinout for you.
Also, the M2-CC3351 and SK-AM62B-P1 schematics may help you understand how everything is connected.
