Other Parts Discussed in Thread: TPS65982, TPS65982-EVM

Can my customer upate FW of TPS65982 from system controller?
Your datasheet(REVISED JUNE 2015) show it can be writen by I2C In 9.2.2.2.1.
Can each I2C port support to update?
And could you give us raw FW data for writing by system controller?

Regards

Yes, your customer can update FW from System Controller, commonly referred to as an EC.

Yes, both I2C ports can be used to update FW.

The I2C1 master should write to CMD1 and DATA1 registers only, while the I2C2 master should write to CMD2 and DATA2 only. This will avoid any potential conflicts if both I2C ports are used.

You can create FW using the web-based Config Tool to modify and download raw FW and update via I2C.

If you require source code for the System Controller, currently we only support Python scripts for the Aardvark I2C Host to demonstrate the FW update over I2C capabilities of the TPS65982. We do not provide or support System Controller source code.

Hi Raja,

I answered this in your other post, but the default I2C slave address for the TPS65982-EVM is 0x38.
