NA6 board communication issues with Mac

[slokart_mx5]

I have a Hellen NA6 board for my 91 Miata.

Before installing the board into the car I went through the steps on the set-up guide to have the board talk with TS. I successfully established communication between the board and TS.

Once I installed the board in the car I started TS before cranking to test sensors and set throttle position. At this point the board the board did not want to communicate with TS. I have since removed the board from the car and it still does not want to communicate.

I tried deleting the project in TS and starting a new one. When I go to select the rusefi_hellenNA6.ini file for the ECU definition, TS does not see it.

Has anyone experienced this issue?

Remove ECU from vehicle, put it on the bench.

Remove top cover. Power the ECU with USB with vehicle disconnected.

Is anything blinking on the board? Do you have any blue LED? Any solid LED?

Working with slowkart, it appears he needs to manual dfu firmware update.

We need to investigate this strategically.

Realistically you you need a Windows device. Before we recover this ECU we need to save the corrupted image for later analysis. Let me prepare some tools while you please find a Windows device but do not recover firmware yet.

Doesn't dfu-util work on Mac?
