Tool/software: Linux

Hi

I am trying to program the flash on the 4 TUSB9261 USB3 SATA bridges that are on my device which is based on the  NVIDIA tegra tx2 platform running ubuntu linux. It has no interface to a PC host. So I can't use any windows SW for this.

Acc. to this link

http://e2e.ti.com/support/interface/f/138/t/341781

it seems like I need the Linux Flash Burner SW and a eBurner driver.

1. Where may I get them ?

2. I see USB HID boot loader device

3. dmesg output

4. Kernel version is 4.4.38

nvidia@voltron-ru-tegra-ubuntu-sn1019:~$ uname -a

Linux voltron-ru-tegra-ubuntu-sn1019 4.4.38-tegra #8 SMP PREEMPT Fri Nov 9 13:01:46 CST 2018 aarch64 aarch64 aarch64 GNU/Linux

5. I'm think it is because the "eBurner" driver is not loaded as I don't see the /dev/TUSB9260_0 node. Is this a driver that Ti provides or is it integrated into the linux kernel ?

6. From the dmesg log

[ 9.614962] usb 2-3.1: Set SEL for device-initiated U1 failed.
[ 9.615480] usb 2-3.1: Set SEL for device-initiated U2 failed.

Is this an error that I may ignore? If not, how do I fix it ? I was hoping once the flash device is programmed, this may go away.

    Hi,

    You are correct. It seems like the firmware has not been loaded on this device. You will need to load your SPI Flash memory with the firmware. I have a Linux-based tool than can help you with this. Please accept my friend request so I can send it to you.


    Thanks,

    Thank you for your response. I accepted your friend request. Will the linux tool you send expect the device need to enumerate as a /dev/TUSB9260 node before it can download the f/w ? If so, I believe I would need eburner driver to load for the device for that to happen - how do I enable that driver in the kernel or is that a loadable module?

    Yes it will. I have the eBurner driver for Linux I will to send it to you as well.

    Nicholaus,

    Thank you. I am working on cross compiling the samples for my platform using the documentation. I am trying to decide which zip file to use from the two you sent. The driver in the non-i386 one seems a little newer.

    In the meantime, I was able to get hold of a SPI-flash programmer adapter from Total Phase called the Aardwark : www.totalphase.com/.../.
    I tried to program the 1.06 FW bin file that I downloaded from the TUSB9261 support page onto the flash using their flash programmer. The flash got programmed and verified ok. But when I power cycle, it still keeps coming back as boot loader. Any idea why the flashed binary is not recognized ? Is the .bin file only meant for download via the USB HID bootloader mechanism and the flash burner tool+eburner app ? If yes, is can you provide a version of the f/w that I can download directly onto the flash chip ?

    Regards
    Shyam

    I compiled the kernel module and ran insmod. The driver loads. I ran the flash burner. It complains saying no compatible devices found. Any idea what is going on ? I already see /dev/TUSB9260_0 device. So why the error. Logs below.

    Shyam,

    As I explained offline , the Linux software is open-source and is provided as-is. The Linux software was not intended your platform, and we do not offer general software support.

    We can continue this discussion offline.
