Bug found while using the REG_Access block from the MAT/TARGET Library

Hi,

I use the REG_Access block to read the value stored in the data register of the SPI1. So I change the 'Peripheral' option from NVIC to SPI1.

But it always goes back to NVIC, once the the simulink model is closed and reopened again. If I don't notice this change and don't manually set it again, it will lead to errors while compiling the code in the IDE.

My software versions are as below:

MATLAB: R2017a

STM32 MAT/TARGET Library: 4.4.2

Best Regard,

Hello, qxj.

Could you please give me more information?

for example:

- which STM32 you use?

- If you provide a little test case if possible or at least an ioc file.

Thanks.

Hello Aimagin,

my board is STM32F4 Discovery Board, but Idon't think this bug is relatedwith the board.

I attached my project. You can finda simulink model (version: r2017a)and an ioc file in the zip archiv.

As you can see, I want to use this block to read the value stored in SPI->DR. But when you re-open the model, it comes back toNVIC.

Thank you for your help!

Best Regards,

qxj

You're welcome.

The same bug still continues in R2020a/R2020b version. Any solution?
