need help getting S34ML04G2 NAND flash to work with lpc1788

I have a custom board with a lpc1788 with IS42S16400F SDRAM and S34ML04G200TF100 NAND flash.
I got the SDRAM to work but the flash won't initialize.
I use the code for the embedded artist oem board. The difference is that the embedded artist board uses the K9F1G08U0C chip and that I don't use buffers.
The command for requesting an id is 0x90 in both chips
When I request the ID of the chip it returns only 1's.

Here's how the flash is connected:
[list]
[*]IO0 to IO7 connected to EMC_D0 to EMC_D7(same as oem1788)
[*]nRE connected to EMC_OE (same as oem1788)
[*]CLE connected to EMC_A20(same as oem1788)
[*]ALE connected to EMC_A19(same as oem1788)
[*]nCE connected to EMC_CS1 + 10k pull-up(same as oem1788)
[*]nWE connected to EMC_WE(same as oem1788)
[*]nWP connected to 3v3(same as oem1788)
[*]nR/B connected to EMC_A23 + 10k pull-up (is not connected on oem1788 )
[/list]

Here is part of my code:


#define K9F1G_CLE   ((volatile uint8_t *)0x90100000)//1<<20
#define K9F1G_ALE   ((volatile uint8_t *)0x90080000)//1<<19
#define K9F1G_DATA  ((volatile uint8_t *)0x90000000)
        
#define K9FXX_READ_ID           0x90

I found the error. It turns out data4 and data5 were swapped. We copied this from an example.
