Forum Post: RE: c6670 SPI NOR boot

Hi Rahul,

Sorry for interrupting you.

I have a question about SPI_Bootloader.zip which you attached to this post.
There nysh.spi.map inside this zip file.

My question is about the nysh.spi.map.
In nysh.spi.map, there are following parameter for PLL.
===============================
* sw_pll_prediv
* sw_pll_mult
* sw_pll_postdiv
* sw_pll_flags
===============================
Which PLL register does these parameter affect to?

And I want to speed up the SPI bus frequency.
At default it looks like the RBL will setup the SPI bus frequency to 20MHz..
For example, if I want to setup to 50.5MHz, is the following configuration correct?
======================
* bus_freq_mhz = 50
* bus_freq_khz = 500
======================

best regards,
g.f.
