Non-volatile setting for SNVS_LP register

[keithmo]

Hi,

I'm using the imx6ul chip and would like to change the SNVS_LP Control register (LPCR) to have an ON_TIME of only 50ms (default is 500msec.)

I can change it easily using device tree/in software. However, I'd like to have this setting saved as non-volatile. As a result, I'm wondering if this setting could be saved permanently (e.g. through fuses) and if it's possible, how to do it?

Thanks!

Hi Keith

SNVS_LP registers are retained when provided SNVS_IN voltage,

I am afraid there is no special fuse for that. Available fuses are described

in Chapter 5 Fusemap i.MX6UL Reference Manual.

Hi Igor,

OK, thanks, I figured as much but wanted to verify.
