PMIC test in u boot for IMX6UL

[anshulkhare]

Hello All,

Good day to you!

My requirement is to test PMIC (PFUZE3000) in u boot for IMX6UL board.

The pmic command is enabled and working in u-boot.

What test I can perform on PMIC? for eg: can we read the voltage values?

Could anyone kindly provide us with some information on this. Any help on this is much appreciated.

Thank you.

Hi Anshul 

one can look at examples in uboot:

pmic_reg_read() in function power_init_board() in uboot/board/freescale/mx6ul_14x14_evk/mx6ul_14x14_evk.c
http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/tree/board/freescale/mx6ul_14x14_evk/mx6ul_1...

and add custom functions for reading pmic registers.

Best regards
igor

HI igor,

Thanks for your reply.

Does pmic command in u boot do the same thing?

"pmic read" allows to read values from the registers.

Is there any way we can read voltage values?

Hi Anshul 

there is no way to read voltages as  PFUZE3000 does not

have adc, only registers.
