Part Number: TMS570LS3137
Other Parts Discussed in Thread: TMDS570LS31HDK, HALCOGEN

Dear TI team,

I am using TMDS570LS31HDK board, and want to use EMIF to interface with an external device which has 8 data line ,8 address line.

The external async device which i used is MaxLinear's XR16L788.  

How to set async config and timing in halcogen and how to send address to this device and read/write data from the external device?
Many thanks !

    Hi Yiying,

    To interface with 8-bit external memory, the EMIF_BA[1:0] should be connected to memory address [1:0], and EMIF_A[5:0] connected to memory address [7:2].

    Your HALCoGen EMIF configuration is fine except the EMIF clock. Please lower the EMIF clock to 50MHz.
