Dear "Ayman M. El-Khashab",
In message 20081021162030.GB22117@crust.elkhashab.com you wrote:
I should have mentioned that we have DEBUG enabled and we've also run the RAM test that is included in u-boot. The ram test does pass.
Please see the FAQ, entry # 1. Passing the RAM test does not mean anything when it comes to accessing the RAM in burst mode.
I am not familiar with those, I thought that once the SDRAM is operating you cannot alter those calibration and timing/delay registers. Is this calibration something that is enabled in u-boot or just via the register accesses to the memory controller?
How about reading the code?
Best regards,
Wolfgang Denk
