Flexram EEPROM Read Fault

pbaierlac — Mon, 09 May 2022 14:59:32 GMT

Hi, I am using the MK10DX256VLQ10 processor. I have configured my FlexRAM to be 4K of EEPROM.

I am having issues getting periodic Bus Faults when reading from my EEPROM, I am verifying that EEEREADY is set before I start reading. The error typically occurs after everything has been running for a while. It appears to be a timing issue, but I am not sure how to prevent it. If I attempt to read an EEPROM value too quickly after a write function was completed I seem to get the bus fault.

After reading the reference material I was not able to find a flag that states the EEPROM is available for reading.

You can refer to \driver_examples\flash\flexnvm_eeprom example in SDK

Hello,

Thanks for pointing me to this, however, I am working with a 3rd party who provided my initial code base that enables the GPIO pins. This file was not provided.

Is there a location I can download this from?

Thanks,

Paul
