LAUNCHXL-CC1310: Help with programming pages in external flash memory.

Hi J,

You could extend our existing NVS SPI driver (NVSSPI25X.c) using the data from your flash device.

Note that we have an existing example that interacts with the external flash on the board: https://dev.ti.com/tirex/explore/node?node=A__AOUUZIR3LDs5ywYsZkvDRQ__com.ti.SIMPLELINK_CC13X0_SDK__eCfARaV__LATEST

Hello
I have reviewed the nvsexternal example and ran it on my CC1310 Launchpad. I was expecting to see the message
“SimpleLink SDK Non-Volatile Storage (NVS) Example” after disconnecting in the debug session, knowing that the application wrote it to memory, but every time I reset the card it continues to just print the following.

Sector Size: 0x1000
Region Size: 0x20000

Writing signature to SPI flash...
Reset the device.

Any possible reason why I don't see the message that is supposed to be written to an external NVS region?

This is a picture after several attempts to reset the device.

Hi J,

Do you see the same when trying out the project from CCS Cloud? Because on my side, it works:

Can you also share a picture of the Launchpad that you are using?

Hi Arthur.

I have tried it again without success.
I have also run the same example in its version for the CC1312R1_Launchpad board and it works fine on that platform.

I should mention that on my custom CC1310 board I have also written my own functions to handle the IS25LP64A memory, so I am only successful in performing read operations. For some reason the write fails and I am unable to understand and detect what is failing on both the Launchpad and my custom board.

Hi J,

I was wondering if the write latch was enabled in the IS25>

Can you check that it is the case?

Regards,

Arthur
