DLPC350 PROMv2.0 software compatibility

Other Parts Discussed in Thread: DLPC350

Hello,
I am considering to upgrade firmware PROMv1.1 to PROMv2.0 in DLPC350.
Question)
Does the timing of PROMv1.1 I2C commands might be different from PROMv2.0?
Or, do we have to evaluate existing I2C commands?

Because, we have already produced our system into the market.

Best regards, RY

RY,

The timing of the I2C transfers and commands are the same between version. The new version adds a couple new commands. The details of the changes are in this post.

Hello RY,

Except Validate Data Command (I2C:0x7D) there is no changes as far as response time is concerned. We would still recommend you to do the basic sanity checks for the I2C control interface for your used I2C command set.

Regards,
Sanjeev
