cpu is am3354.
my nor flash size is 256MB (S70GL02GS12FHI010).
I have configured the GPMC module for 16-bit, AD multiplexed NOR device.
I use Asynchronous Single-Read/Wite Operation on an Address/Data Multiplexed Device
I use Pin mux utility tool showing IO SET violation on using gpmc_ad(0-15) and gpmc_a(1-10)_mux0.
But gpmc_a(0-7)_mux1 gpmc_a(16-11)_mux1 used for lcd module.
Please help to clarify the following questions.
Q1.I'm not sure gpmc_ad (0-15) whether gpmc_a (1-10) _mux0 available.
Q2.The setup time of the cs and adv, oe signal from there? If it depends on RDACCESSTIME start time?
This is Read on an Address/Data-Nonmultiplexed Device.Do we face any issues? Is it correct?
Q3.new I can't get the device ID and When I run my board, I not get adv signal，it kept low level. I don't know why?
To program this configuration we would do:
GPMC_CONFIG1_0 = 0x1200
GPMC_CONFIG7 = 0x40
GPMC_CONFIG6 0x402C1
Is it correct?
