<DIV><FONT size=2>Hi, all!</FONT></DIV>
<DIV> I am doing porting jobs on GX2(GX-<A
href="mailto:GX-533@1.1w">533@1.1w</A>) + cs5535. I am using OLPC/rev_a
directory as my starting point. </DIV>
<DIV>I know that OLPC use GX2(GX-<A href="mailto:GX-500@1.0w">500@1.0w</A>,
right??) + cs5536. From POST card i see the code runs far behind the code </DIV>
<DIV>of auto.c(src/mainboard/olpc/rev_a/auto.c), and there should be some
information printed from uart1, actually there is </DIV>
<DIV>none. </DIV>
<DIV> As for cs5536, i see cs5536_setup_onchipuart() called
before uart_init(), and i find the MSRs handled in </DIV>
<DIV>cs5536_setup_onchipuart do exist in cs5535. So i added a function named
cs5535_setup_onchipuart in </DIV>
<DIV>cs5535_early_setup.c, and call that functions in auto.c. The same result,
nothing printed from uart1.</DIV>
<DIV> I googled related information, i found someone said
we must first loaded VSA before we can use internal uart of </DIV>
<DIV>cs5535. I have a little bit understanding on VSA. From my point of view, i
see VSA is an auto tools for OS to access </DIV>
<DIV>standard x86 compatible registers and ios from not fully x86 compatible
system like cs5535. And i think </DIV>
<DIV>cs5535_setup_onchipuart handles accessing msr in cs5535 manually as what
VSA should do and we do not need to </DIV>
<DIV>firstly load VSA at auto.c. If I were right, why nothing appears from
uart??</DIV>
<DIV> Any advice would be well
appreciated.</DIV></FONT></DIV>
