Hello,

I don't see this behavior on my setup while using a freshly installed SDK version 8.3.0.18 and sysconfig 1.13. 

In any case, the error that you see normally happens because there is no support for the device you are trying to select in the sdk and/or sysconfig does not contain the metadata of this device. We have a guide on how to add support for custom devices since the software packages normally just come with support for the flash devices that are in used in our EVMs. In this case, the W25H512J device is not part of our EVM so sysconfig and the SDK should not be able to recognize it. the above behavior is expected assuming that you didn't add device support yourself. What I don't understand is why the device shows up in the first place.

I would suggest the following: 

• download the latest SDK, and follow the instructions in the following page: AM273x MCU+ SDK: Adding Support For a Custom Flash Device (ti.com)
• If you do not want to download to the latest, and decide to keep using version 8.03.0.18 of the SDK, then follow instructions here instead: AM273x MCU+ SDK: Writing flash driver for a custom flash device

Both links above are the same guide for different versions of the SDK, but the process has changed since 2022, hence the updated guide. 

If above doesn't work, then please confirm your version of CCS here.

Best,

Daniel

hello Daniel

Thank you for replying, I did not add device before.

The device shows up in the first place because I manually changed some configuration codes, and those codes originally needed to be configured by sysconfig. Anyway, I followed your connection guide to add the device first.

best regards

Alisa

Hello Alisa,

thanks for confirming, let me know if following the guide fixes the problem

Best,

Daniel

Hi Daniel,

I follow the steps you provided, and met this error in "

Step 4: Test the new flash driver with the changes using QSPI Flash transfer example

"

Hi Daniel,

I found there are no gFlashNorQspiAttrs_W25H512JV and  gFlashNorQspiDeviceDefines_W25H512JV symbol in board.am273x.r5f.ti-arm-clang.debug.lib 

It needs to rebuild board.am273x.r5f.ti-arm-clang.debug.lib probably. Could you please tell me how to rebuild board.am273x.r5f.ti-arm-clang.debug.lib?

Here is the symbol list of board.am273x.r5f.ti-arm-clang.debug.lib

Hi Daniel,

It works well after following your commands, thank you so much~

Hi Amy, 

Glad it works! if you have more questions feel free to open a new thread

Best,

Daniel
