EVL4248-QV-00A - No SMBus communication

[m.wachs]

Hi,

i want to read/write the device but i could not get the communication working.

I have checked the SCL/SDA signal @R11R11/R12 and i measured it on Pin1(SCL) Pin2 (SDA). Everything seems fine but i do not get any acknowledge from the device as you can see in my screenshot.

I tried all possible device addresses, different clocks (100kHz in the screenshot) but no success.

Maybe you got any idea.

I also did a test with a Maxim Powertool that does a scan on the bus:

Maybe my devkit is broken?

found it:

The SCL pin was not soldered. (hopefuly you can see it)
