Hi,

We are  facing an issue with SDRAM(IS42S16400F) on Hitex board LPC1850EVA-A4. If  run with 72MHz clock then  data write/read from SDRAM is correct. But If  increased to 120MHz the data write/ read is not correct.

The clock is increased to 120MHz by setting the PLL1 using API  “CGU_SetPLL1(10)”  in CGU_Init() function.

Please help in resolving this issue.
