Hi BU experts.

Since customer having issues in USB DFU in the related thread, they also tried using sbl_uart_uniflash.

Any idea what might be the problem here?

Hi Hang,

Please ask the customer to use the correct images according to the device type. It seems the customer is working with HSFS device so the customer needs to use the HSFS images (`hs_fs` in the extension).

Regards,

Prashant

Hi Prashant,

Customer is now using hs_fs image, but still have the same issue.
