Hi,
Has anyone ever tried talking to the LTM4677 chip on the Arria10 SoC Dev Kit Board? I’ve been successful in getting info out of the MAZ1619 via i2c-tools, but the LTM does not respond to i2c-tools commands. My assumption is that it requires PMBus API commands to be called. I can’t seem to find a convenient PMBus library recipe to build into my image.
If anyone has done this, and can share some tricks, it would be appreciated. Otherwise, if someone can point me to a recipe for PMBus API that can be built into Angstrom, that would also be appreciated.
Thanks!
