I am working to recognize mass storage device(M.2 (SATA III) 256GB innodisk) using TUSB9261

I am using imx8 board and system is linux.

My problem is always recognizing bootloader mode.

I entered command lsub and result is "Bus 001 Device 003: ID 0451:926b Texas Instruments, Inc. TUSB9260 Boot Loader"

So linux system does not recognize mass storage.

How to debug it?

For example, I want to check that TUSB9261 recognize SATA device.

Hello,

In addition to David's answer. I would say that in general we do not offer software support for this device. The TUSB9261 source code is available on the product page here: TUSB9261 data sheet, product information and support | TI.com

Let me know if this answers your question.

Regards,

Nicholaus

Thanks for the advice. I solved it. The spi's data line was disconnected.
