IWR6843ISK: Regarding the QSPI flash read and write issue in IWR6843isk

Vasudev Kencharadder

Part Number: IWR6843ISK

Tool/software:

Hi Teams,

I am working with the IWR6843ISK and using the Out-of-Box (OOB) Demo Code. I want to use the mmwDemo_flashWrite and mmwDemo_flashRead functions to write and read specific values to/from the QSPI Flash.

I have implemented the required code for these operations, and there are no errors during compilation or runtime.The flashRead and flashWrite functions are used for Calibdatatsave and Calibdatatrestore,there also if I print i am getting 0xFFFFFFFF

However, the values I am reading back are always 0xFFFFFFFF, instead of the desired values that I attempted to write.

I would greatly appreciate any guidance or suggestions on troubleshooting this issue.

Thank you!

Hello.

Have you tried running the qspiflash test examples in SDK 3.6 to see if it is resulting in the same behavior? And have you tried running the application in debug mode to see what values are getting loaded from SFLASH during the flashRead? Please keep in mind that your application is also stored in SFLASH so make sure that you are writing to a location where you know the application is not located and also try first writing zeros to the location before writing data and then reading from that location in case there are default values in memory.

Sincerely,

Santosh
