QSPI FLASH Init time out

Saitej — Mon, 08 Feb 2021 15:31:29 GMT

Hello

Am using NXPS32K148 Q176 EVB, and trying to run qspi_external_flash_s32k148 example project after depopulating R272,R260,R208,R210,R212,R250 & populating R271,R254,R209,R211,R213,R244.

Now am seeing FLASH_MX25L6433F_DRV_Init function status is TIME_OUT,

please help me on how to verify my corrections are correct and why am seeing TIME_OUT

Hello,

Do you have the problem with the unmodified qspi_external_flash_s32k14 example?
Or do you have you own code?

Is the external flash powered (P3V3_SW)?
Do you supply the board with 12V?
In which position is J18?

Thank you,

BR, Daniel

Hello @danielmartynek

Am using example project without any modifications to it.

Is the external flash powered (P3V3_SW)? - Yes am able to see 3.3V in between pin 4 and pin 8 of IC U508

Do you supply the board with 12V?- No it is powered with USB.
In which position is J18?- J18 is placed in between Pin 2 & 3.

Hello,

Can you please find out which function returns the TIMEOUT status?

The FLASH_MX25L6433F_DRV_InitDevice() function calls several functions that can return the error code.

Also, please double check all the resistors that you replaced.

Regards,

Daniel

Hello @danielmartynek

Thanks for the response,

Yes, cross verified all the resistors are in place as guided, Here am seeing STATUS_TIMEOUT from "FLASH_MX25L6433F_DRV_WriteEnable" function.

Sorry, one more question.

Which version of the SDK / S32DS do you use?

Thanks,

Daniel

SDK- V3.0.0

S32DS- V2.2

Hi,

I get the same error in S32DS2.2 with SDK 3.0.0 on an EVB with the original ENET routing.

There must be a hardware issue. Can you scope the bus on the U508 pins?

Regards,

Daniel

Hello @danielmartynek

Yes, I can with me logic analyser is available. Can you please guide me on what exactly I need to look into.

Hi,

This is the function:

It sends WREN twice and reads RDSR twice.

The STATUS variable is either overwritter to STATUS_SUCCESS if WEL is set by the WREN command or there is another error reported by the QSPI driver.

I reckon the issue is that WEL does not get set and the STATUS variable stays in the default STATUS_TIMEOUT.

You should see this on the bus:

2x WREN

2x RDSR

Daniel
