Hello community,
I'm trying to configure GPMI NAND I/F timing for i.MX6Dual.
Current GPIM_TIMING0[DATA_HOLD]=3 and GPIM_TIMING0 register value is a 0x00010303.
But write cycle waveform output only 1cycle width.
Other bit value, GPIM_TIMING0[ADDRESS_SETUP] and GPIM_TIMING0[DATA_SETUP], seems correctly.
Do you have some checkpoint to solve this problem?
Best regards,
Ishii.
Hello jamesbone
Thank you for your reply and sorry my late reply.
This problem occurs by u-boot setting.
NAND device is a Macronix MX30LF4G18AC .
Best regards,
Ishii.
Hello,
Are you doing the setup for Uboot? or directly in the DTS,? which NAND memory you are trying to use?
