Hi
Now I use OMAP3530's GPMC to connect with Gigabit Ethernet Controller AX88180.I only can use the 16bit nonmultiplex asychronouse mode based on my hardware.
AX88180 at least need 8kbytes space in 16bit mode.But OMAP3530 only has A1-A10,I used 5 gpios to control the high 5bit of the 88180's address bus.And I configed GPMC_CONFIG1_i~GPMC_CONFIG7_i.
The result:I can't read anything from AX88180.
Are there some wrongs in my doing?
In OMAP3530 datasheet,"When the GPMC.GPMC_CONFIG[1] LIMITEDADDRESS bit is set to 1, only gpmc_a[10:1] address
lines are used. This limits the memory support to 2K-byte addressable memories."Maybe OMAP3530 can't connect with AX88180.
Please help me!
