How to configure an external static memory controller for lpc4330?I tried to write it, but I didn't succeed.The following is my configuration code,please advise

void Board_ExSram_Init(void)
{
IP_EMC_STATIC_CONFIG_T Static_EMC_Config;

LPC_CCU1->CLKCCU->CFG = (1 << 2) | (1 << 1) | 1;
while (!(LPC_CCU1->CLKCCU->STAT & 1));

if (SystemCoreClock < 80000000UL) {
LPC_SCU->EMCDELAYCLK = EMC_CLK_DLY_TIM_0; /* No EMC clock out delay */
}
else {
LPC_SCU->EMCDELAYCLK = EMC_CLK_DLY_TIM_2; /* 2.0 ns EMC clock out delay */
}
/*emc pin config*/

Hi,

Thank you for your interest in NXP Semiconductor products and

for the opportunity to serve you.

Can you tell me the product number of the external NorFlash, and whether you describe what exactly issue you encounter.

Have a great day,

TIC
