PCA9640A driver source code and uPower firmware software package

[Ajith_Ali]

Hi,

Currently I am using custom hardware with iMX8ULP processor and I am using PCA9640A PMIC.

I have to modify some changes in the PMIC source code according to my career card requirement.

While checking I found a document to custom build uPower.bin following the document https://www.nxp.com/docs/en/user-guide/uPower_USERS_GUIDE.pdf

In this document, it has been mentioned to cross compile using riscv. Please refer section 10.3.1 Preparing the uPower software build environment 

Here it is been mentioned that NXP release a package includes the PCA9460 driver source code and basic uPower firmware static library. If the user uses other PMIC chips, it is not difficult to port the PMIC driver.

I am not sure where to get this software package with PCA9460 driver source code and uPower firmware static library.

Please help me in the right way to get this software package so that i can do my modifications accordingly.

Regards,

Ajith Ali

Hello @Ajith_Ali 

Hope you are doing very well.

Sure, please take a look to the Embedded Linux for i.MX Applications Processors web page.

There is the uPower Firmware Porting Kit 1.3.1:

Inside is the PMIC_driver Porting guide and the uPower firmware binaries.

Direct download link of the uPower Firmware Porting Kit 1.3.1.

Best regards,

Salas.
