Master is driving the clock and MOSI signals but we are not seeing any response from Flash.

Hi,

We are using S29GL064N NOR Flash chip in our new product.
We are facing one issue, in which after Erase_Confirm command some times randomly we are getting FLASH_DEVICE_SUSPEND state.
Normally it should go in FLASJ_DEV_BUSY state.
This happens when toggling of Toggle_Bit I(DQ6) stops, but Toggle_Bit II(DQ2) still toggles causing the device go in FLASH_DEVICE_SUSPEND state as per the code.

Is this kind of error which is known for this device or needs to handle differently?
We see this happens randomly after few erase cycles and not always.
Please help us for solution you have for this.

Thanks and Regards,
Anil Patil
