Disable data cache on mpc5200

Hi,   we have troubles with our 256 MBytes DDR SDRAM on our mpc5200B custom board.   On this processor we have four chips, 64 MBytes each connected via chipselects CS0 & CS1. When running a specific memory test under u-boot the CS1 connected RAM seems also to work fine (memcpy, memcmp, etc.

MPC5200B memory performance

controller interface. All in all, I am not sure, why the memory access is so much slower than I expected. Which factors did I miss in my calculation ? Can anybody run this program on its 5200B based board as a comparision ? Best regards, Daniel Schnell. memcpy_perf.c Description

rap,memcpy on the linker line to replace all occurences of memcpy, memcmp, etc. also for external libraries. Best regards, Daniel Schnell -- Daniel Schnell | [EMAIL PROTECTED] Hugbúnaðargerð | www.marel.com -Original Message- From: [EMAIL PROTECTED] [mai

RE: Where is initial console initialized ?

Hi, Well if one does it right, then things work as expected. I simply chose the wrong Kernel configuration, the correct console driver has not been compiled in. Now it works as expected. Sorry for the noise. Daniel Schnell. -Original Message- From: Domen Puncer [mailto:[EMAIL
