LPC4337 SDRAM Configuration

Question asked by Sigurd Möller on Aug 5, 2016

I have been trying hard to make the correct configs for my SDRAM. All connections are correct and so are the pin muxings.

 

at http://pastebin.com/YupajrwX it is possible to see my SDRAM config function.

 

in my main function I run http://pastebin.com/n1UMgbid

 

Value to write into each address is 0xAB000000
NWords is just set to 32 to begin with.

 

In this test-function i get:
"Error at counter = 1"
"Error at address 0x28000000"
"Data at address 0x28000000 is 0xABABABAB"

 

If I select value to be 0xBB000000 i get "Data at address 0x28000000 is 0xBBBBBBBB"

 

It is always the two digits to the left that gets "mirrored". Any ideas what I am doing wrong?
