Hi Karan,

Whether it is necessary to run,

uic68347@igl5718u:~/oti-processor-sdk-linux-j7-evm-08_00_00_08$
uic68347@igl5718u:~/oti-processor-sdk-linux-j7-evm-08_00_00_08$ make dra7xx_evm_defconfig
make: *** No rule to make target 'dra7xx_evm_defconfig'. Stop.
uic68347@igl5718u:~/oti-processor-sdk-linux-j7-evm-08_00_00_08$ make menuconfig

Hi Viswa,

You can use the SDK Makefile to do this.

cd <LINUX_SDK_PATH> //this is where you have the board-support, linux-devkit etc and also a Makefile.

make u-boot

Karan

Hi Karan,
   I created the u-boot with the steps  you specified.

Connected the USB3.1  Type c

Hi Karan,
 Pls let me know if there is mistake in  the switch position because I couldnot find the device using the dfu-util -l command?  Also let me know after loading till the u-boot , whether i need to use the NFS to load the kernel?

Regards,
Viswa

Hi Viswa,

The boot switch setting are incorrect. Please refer the appnote https://www.ti.com/lit/an/spracy5/spracy5.pdf table 3.1 for the switch setting.

You need to apply the patches as mentioned in https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1041155/faq-tda4vm-j721e-j7200-enabling-dfu-boot-on-8-0-linux-sdk then rebuild u-boot and use this to send over usb.

Regards

Karan

Hi Karan,

  I changed the switch as specified in the switch as specified in the document. im able to find

Hi Viswa,

It could be some issue with your git repo.

Please try:

git am --abort

Then try to apply patches one by one in the dfu-fixes folder.

Let us know if that works.

Hi Keerthy,

  It is not working. Patch file is not being applied since the lines are different in the source code and the patch file.

We are using the ~/ti-processor-sdk-linux-j7-evm-08_00_00_08 version.

environment: ti: k3_dfu: Increase the size allocated for bootloader images in dfu_alt_info_ram

The size of u-boot.img is above 1MB and that of tispl.bin is close to 1MB,
in case of j721e. Therefore, increase the sizes allocated for tispl.bin and
u-boot.img to 2 MB and 4 MB respectively, in dfu_alt_info_ram environment
variable.

Hi Viswa,

Can you please update the latest on this thread?

Are you not able to apply the patches mentioned in the e2e below and enable dfu boot on SDK8.0? If some patches are failing, can you manually make the modifications?
