Hi There,

Does anyone know if the DM355-270 can run  at full speed and have reliable 
SD/MMC module behavior?


 We are using the 270 MHz variety of the DM355, clocked up to 270MHz. Now, the 
SD/MMC module claims that it only supports a module clock speed up to 100MHz, 
but running at 270 MHz produces a module's clock of 135 MHz. 

Since the sysclk2 divider is a fixed, to even get close to spec (108MHz) one 
would need to clock the ARM down to 216MHz... and start asking why we paid more 
for the 270 MHz part :)

I see mostly good behavior on SDHC cards when we are over clocking the module 
at 135MHz, but get cards every now and again that throw buffer IO errors on 
data read timeouts. Anyone vouch for 135 MHz module clock working with a 
variety of SDHC cards?

Thanks,
Paul
