Linux/TUSB9261: Unable to program when using TUSB7340

Part Number: TUSB9261
Other Parts Discussed in Thread: TUSB7340,

Tool/software: Linux

Hi,

We have the linux flash burner tool, and when attempting to program the device through the TUSB7340 it fails to program. However, if we use a different USB port on the same PC (i.e. not through the TUSB7340) it programs perfectly.

The tool believes it has sent all the data across correctly, and prints out that it has programmed successfully, however on reset or power cycle the TUSB9261 is still not programmed.

This is seen using the TUSB9261 and TUSB7340 demo boards

Similar behaviour is seen on a custom board of ours where the TUSB7340 and TUSB9261 are daisychained.
