11:14 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Increasing CPU clock OMAPL138: Hi Mike,
Ah, makes sense.
For the time being I'll stick with controlling the clock frequency with Linux.
Thank... Kim Nielsen

07:03 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Increasing CPU clock OMAPL138: Hi Kim,
I think the reason why the uBoot Critical Link publishes is using 300 MHz is because the Revision 1 silico... Michael Williamson

02:12 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Increasing CPU clock OMAPL138: Alright.
Is there is no way to change the default frequency from 300Mhz to e.g. 372MHz with U-Boot?
As far as I ... Kim Nielsen
02:01 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Increasing CPU clock OMAPL138: Hi Kim,
I think the issue is that the voltage scaling needs to be done to default
to a higher frequency.
The P... Michael Williamson

01:44 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Increasing CPU clock OMAPL138: I actually got another question.
By default, the cpu frequency seems to always be 300 MHz.
