MCU-PLUS-SDK-AM243X: USB DFU Bootloader

Hao Wang

Part Number: MCU-PLUS-SDK-AM243X
Other Parts Discussed in Thread: UNIFLASH

Tool/software:

I use DFU mode to write firmware to Soc RAM in AM243x-evm board.

I have installed dfu-util 0.9 64bit for Win10 and installed Zadig for WinUSB driver.

Because we do not have admin to run sudo command for duf-util execution, I have to run the below py code to boot from USB and send the appimage follow the description in SDK manual.

python usb_bootloader.py --bootloader=sbl_prebuilt/am243x-evm/sbl_dfu.release.hs_fs.tiimage --file=< path to multicore appimage of application binary

It seemed bootloader was initialized.

But it then said the dfu suffix is invalid, then held on waiting for dfu to be enumerated.

When repeat above procedure, it seemed the bootloader even cannot be functional again.

Can you please specify more reasonable procedure?

Thanks.

Hello,

Can you please run the following command and let me know the logs:

dfu-util -l 

Apart from this please tell me if things work fine if you put your bootloader and the appimage in the file default_dfu_ospi.cfg and use the usb_dfu_uniflash.py script.

Regards,
Vaibhav

Thanks for reply.

When I run dfu-util --list, it gives me:

dfu-util 0.9

I have tried the usb_dfu_uniflash.py as you recommended.

It always holds at waiting for dfu device to be enumerated.

Please let me know how to install dfu-util in Win10 properly.

Thanks.

Hi,

The logs when you run the above mentioned command should have been as follows:

I have tried to install USB DFU driver by Zadig. I think this can resolve the installation.
But when set the soc boot mode as DFU. The DFU port cannot be detected in Zadig tool. It either cannot be detected in System Device Manager.
Do you have experiences on this that can be shared?
Thanks.
