RM46L852: HALCoGen not showing all the EMIF address pins

Part Number: RM46L852
Other Parts Discussed in Thread: HALCOGEN

Hi,

I am trying to use the EMIF interface to talk to external FPGA. There are 12 address lines to be used.

While trying to generate the code for EMIF configuration using HALCoGen, I did following:

1. Enabled the driver for EMIF,

2. In EMIFtab, selected enabled EMIF ASYNC1 module

3. Here is the issue. When I try to Enable EMIF peripheral in PINMUX tab, it shows only 5 EMIF Address pins; EMIF_ADDR_0, EMIF_ADDR_1, EMIF_ADDR_6, EMIF_ADDR_7, EMIF_ADDR_8. It is not showing EMIF_ADDR_2-5 and EMIF_ADDR_9-12.

How to enable those pins in HALCoGen?

Any help would be appreciated.

Thanks,

Avinash

    Hello Avinash,
    Not all EMIF pins are multiplexed and you don't have to configure these pins.
    Here are multiplexed pins that needs configuration:
    EMIF_nCS[0]/N2HET2[7]
    EMIF_nCS[3]/N2HET2[9]
    EMIF_BA[1]/N2HET2[5]
    EMIF_ADDR[0]/N2HET2[1]
    EMIF_ADDR[1]/N2HET2[3]
    EMIF_ADDR[6]/N2HET2[11]
    EMIF_ADDR[7]/N2HET2[13]
    EMIF_ADDR[8]/N2HET2[15]

    EMIF pins are described in Table 4-42 External Memory Interface (EMIF) of device Datasheet ( www.ti.com/.../rm46l852.pdf )


    Best regards,
    Miro
