I work on the MPC5645S evaluation board.
I have written a DRAM driver.
I have noticed that the DCU can access this DRAM because when I modify the content of the DRAM, the TFT changes color.
On the other hand, I cannot have the E200z4 core write in it.
Also, the DRAM tests that I performed with the Green Hill debugger is OK
My ram is mapped at address 0x20000000. I hope that the DRAM at this address can be be accessed by the e200z4
Has anybody got a clue of what may be happening?
