TPS65224-Q1: Linux driver and full datasheet

Olof Winge

Part Number: TPS65224-Q1
Other Parts Discussed in Thread: AM62P, TPS65224

Tool/software:

We are looking to use the TPS65224 together with the AM62P using the TPS as a watchdog.

I have two questions, is there a linux driver available for the pmic watchdog functionality?

Is there a more detailed datasheet than what is available at the product page since that datasheet does not seem to include i2c commands / registers and general usage instructions.

Thanks in advance

Hi Olof,

for drivers please see this FAQ. The full data sheet is available in the secure folder for which you can request access in the product page. Direct link to request form here. In that folder you will also find the user's guide for the TPS6522430/TPS6522230 which has all the configuration specific settings and instructions.

regards,

Niko

I have read that FAQ and unfortunately it doesn't answer my question.

As far as I can tell that code is only for freertos, not linux. I am asking specifically about a linux driver.

Hi Olof,

I believe that you will want this https://www.ti.com/tool/PROCESSOR-SDK-AM62P Then scroll down to PROCESSOR-SDK-LINUX-AM62P for the Linux version. I think this also should have pmic drivers.

Regards,

Katie

Thanks Katie.

As far as I can tell from the source here there are some drivers for the PMIC, like i2c and gpio. But not for the watchdog functionality.
