Hi,

I use the Cypress SRAM "CY62167DV30" 1M x16 bit on LPC1857 paltform.
On 16-bit mode is incorrect output , and I try modify hardware to 8-bit mode.
On 8-bit mode is working fine.

I attach the schematic and code.

Would you please tell me how to solve this problem.

Thanks so much.

Hi bavarian,

Thank you for your comment.

We have to solve the problem.

We try to change the register " STATICWAITOEN0" to zero , then the memory testing is working fine.

Have a nice day.

I don't see major mistake in you configuration, but the buffer needs to be enabled:

LPC_EMC->STATICCONFIG0 |= 1 << 19;
