Compiler/CC2540: After downloading UBL boot, CC2540 cannot be recognized as U disk in Linux.

Part Number: CC2540
Other Parts Discussed in Thread: CC2531,

Tool/software: TI C/C++ Compiler

After I downloaded the boot of UBL on the Bluetooth chip, our master chip (Linux system) did not correctly identify it as a USB flash drive, so we have no way to perform the upgrade operation on the master chip.

As shown, I used the USB driver provided by my host, but I did not see the device I wanted in the /dev/ directory.

But I can correctly identify it as a USB flash drive under Windows, and can upgrade HostTestReleaseCC2540USB-UBL.bin and it works fine.

Hi Dashi,
I am not certain why it does not work or if it should work. Have you tried different machines?

We have tried various Linux distributions using UBL, which are:

1. linux 3.3.81. 2.Ubuntu 14.04.6 LTS

Linux 3.3.81 has no symptoms, there is no need in the /dev/ directory.（The problem we need to solve）


Ubuntu 14.04.6 LTS：

Insert the usb-dongle into the usb port of the host computer. The driver used is usb-storage.

1. The device was successfully identified as a block device, associated with the device file /dev/sdc

2. The driver and device negotiation process is in error.

The kernel output information is as follows:

Linux system basic information

Hardware: CC2540 (UBL firmware)

Kernel:Linux version 3.3.8

To support the U disk function, open the kernel as follows：

SCSI device support

SCSI disk support

USB Mass Storage support

Hey,
I am not familiar enough with Linux to aid with this. maybe the community or someone else knows what is going on. I'll leave this thread open for a while.

Hi,
There seem no be no support for Linux with the existing driver.
