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.
