Hi Diego,

I found LPJ information from kernel/Documentation/kernel-parameters.txt.

I read that improper settings of LPJ value can damage the board and
affect its performance.

 

For two boards with same hardware and software configuration lets say
their LPJ value differ by some tolerance.

What will be the overall effect of setting incorrect LPJ value on second
board in terms of performance, booting time?

 

Thanks.

Hi,

 

LPJ can't damage your board AFAIK, where did you find such reference?

 

It's only a calibration value that is calculated at boot time but it
won't hurt your board. Be aware that this value will be different
depending on the clocking of your system.

 

Regards,

 

Diego.

Hi all,
I want to reduce bootup time on DM355 based board.
One of the technique is to use correct LPJ value in the bootargs.

I have found how to get LPJ value on our board.
But there is one caution that if we use incorrect LPJ value it might
damage the board.

So I want to know what should be allowable range of LPJ value which will
not damage the board and helps in reducing bootup time.
Like suppose LPJ value for my board is 538624, but lets say I am using
(538624 +/- 50) than it won't affect my board and if I am using
(538624 +/- 100) or more that it will damage my board.

I want to know acceptable LPJ value range on DM355 based board.

Thanks in advance.


Regards,
Jitendra
