Hi all,
I have two SDRAMs on my customize board. The CS pins are IOMUXC_GPIO_EMC_29_SEMC_CS0 and IOMUXC_GPIO_B0_02_SEMC_CSX03, and the start address are 0x80000000 and 0x8C0000000, respectively.
I used semc_sdram example code to set both of them. And the SDRAMs can be read and written correctly.
Next step, the semc related registers were read out and recorded. So I filled out these values to dcd.c and comment out BOARD_InitSEMC(). However, the values read from the second SDRAM were wrong (the first SDRAM is okay). And I have localized the problem which comes from Mode setting in dcd.c. But the IPTXDAT of the second one is the same as the first one, so I cannot ffigure out the reason.
There is a question I need to make sure. Could I initialize two SDRAMs by dcd.c, or just one?
my dcd.c:

Hi @MCW ,
Yes, you can enable two SDRAM in dcd. The RT1170 EVK has two SDRAM too, and they are initialized in DCD. It is needn't to write many SEMC register twice in DCD. You can refer to the dcd file in RT1170 SDK examples.

Jing

Hi @jingpan ,
Thanks for your reply.
It works after I add this code which is related to set IOMUXC_GPIO_B0_02_SEMC_CSX03 in the dcd.c
0x40, 0x1F, 0x81, 0x44, 0x00, 0x00, 0x00, 0x06,
0x40, 0x1F, 0x83, 0x34, 0x00, 0x01, 0x10, 0xF9,
Best regards,
Doris

Hi @jingpan ,
I have one more question. I used the default dcd.c which IOCR defualt value is 0x79A8. And then I applied SEMC_ConfigureSDRAM function to set two sdrams. The read/write result of the second SDRAM was wrong. However, the read/write result was correct when I set the value of IOCR as 0x39A8 in the dcd.c. I have checked the datasheet, 15-17 bits of IOCR register are used for SEMC_RDY function selection. For my customize board, I don't use the SEMC_RDY pin because it is assigned for other gpio function.
Why setting MUX_RDY to 001 has some impacts on the second sdram read/write?
Best regards.

Hi @MCW ,
To MUX_RDY field, 0x00079a8 is same to 0x00039a8. It is bit 17~15, all zero. What different is MUX_CSX3.

Jing
