RM44L920: Error on Uniflash

Yun Hoseong

Part Number: RM44L920
Other Parts Discussed in Thread: UNIFLASH

Hello, I am Hoseong Yun from RS Automation.



I have a problem using Uniflash.

Our board uses two RM44L920 chips (daisy chain).

It also uses the XDS560v2 STM debugger.

Below is the error message.

-----[An error has occurred and this utility has aborted]--------------------

This error is generated by TI's USCIF driver or utilities.

The value is '-182' (0xffffff4a).

The title is 'SC_ERR_CTL_CBL_BREAK_NEAR'.

The explanation is:

The controller has detected a cable break that is near-to itself.

The user must connect the cable/pod to the controller.

[End: Spectrum Digital XDS560V2 STM USB Emulator_0]

what's the problem? please give me some advice.

thank you.

Specifically see:

Technically a cable break is detected by a pin that is grounded when the cable is plugged in. If the pin is on the connector that plugs into the target board, it is often called Cable Break Far or sometimes just Cable Break. If the pin is on the connector that plugs into the debug probe (e.g. the cable pod of an XDS560v2), that is called Cable Break Near.

Check the integrity of the ribbon cable that connects from the pod to the board. Check the connections to the mentioned pin. If you have a spare cable (maybe from the broken pod), you may want to swap out the existing one with the spare.
