TMS320F28377D: Question about EMIF

Green Deng

Part Number: TMS320F28377D

Dear team:

My customer configured the EMIF module according to the routine. After the test, it was found that the data line of the EMIF can be output normally, but the address line has no output.

The configuration code is as follows:

1, GPIO configuration

2, EMIF rigister configuration

3, Variable definition

4, Test code

Best regards,

Green

Hi Green,

If address lines has no ouput, it mostly pinmux configuration issue. Has customer checked the pinmux configuration register value in CCS register view after running the configuration code to make sure it is correct ?

Hi Vivek:

Sorry, the customer made a mistake. The address line has output.

Besides, he has another problem. The start address of CS2 is 0x100000, and the data is 16 bits. The address line uses EM1BA1 and EM1A0-EM1A18 in total.

In this case, does "1" in the address "0x100000" have no corresponding address line?

0x100000 is base address. What EMIF sends outside is only offset so it'll send address 0x0 for 0x100000 and 0x1 for 0x100001 outside.

Hope this is clear.

Regards,

Vivek Singh
