UBL execution sequence



Hi ALL,

 

I have noticed that there is a duplicated configuration for the "UBl*.bin" for the PLL0 and PLL1 as :

1 - In the UBL code itself, there is a function used to configure the PLL0 and PLL1

2- In the AISGEN tool there are two taps for configuring PLL0 and PLL1

so, actually i cannot understand because in my case i need to change the Crystal from 24MHz to 27MHz and in accordingly i need to edit the PLL configuration

Does I need to change in both the UBL source code and the AISGEN tool settings or the AISGEN settings is enough ?

Please note that I use OMAP L138, but I believe t could be general question

 

 

can any one help please.
