Just a heads up and also inquiring if anyone else has seen this.
Ordered 5 more Can Bridges with the blue PCB, all with F105s, They look legit, at least the dies are marked from either China or Philippines,
Cube programmer can write to them, clear, etc. and show up as 0x418 device code.
My working codebase doesn’t show any life on these other units.
Took a firmware dump of my working unit, confirmed the new units have identical code via firmware comparison.
Both have the 25 mhz crystal.
Haven’t dug too deep into it yet, most likely a counterfeit chip, but just need to figure out what’s required to get it running effectively.
