Hello,
I interfaced an FPGA to the SoC via GPMC.
The retained configuration is:
- Asynchronous
- 16 bits
- and CYCLE2CYCLE = 0
Despite this, I observe a very long pause between two consecutive readings.
The registers content is as below:
GPMC_CONFIG1_i = 0x40C11000
GPMC_CONFIG2_i = 0x00121200
GPMC_CONFIG3_i = 0x00000000
GPMC_CONFIG4_i = 0x12001200
GPMC_CONFIG5_i = 0x000F1515
GPMC_CONFIG6_i = 0x80000000
GPMC_CONFIG7_i = 0x00000F52
Is something in my settings that could explain this long delay?
The read transaction is performed through a memcpy (no DMA at the moment).
