Hi all!
In the S32DS development environment, the addition of the DMA RTD module caused the static variable to be incorrectly initialized and the value to be 0. The chip is not operating properly, and it is in HardFault_Handler.
Details are as follows:
After DMA is configured, the content in the screenshot section of the added configuration file may cause this situation.
It causes the static variable to have an initial state of 0 instead of an initial value, as follows:（Observe the variable before it is run and just entered debugging state）
How to set up to avoid this situation? Thanks very much！
Best Regards

Hi VaneB!
Thank you for your attention！
Today I did some careful debugging again and found some problems with the data and bss initializer functions.（init_data_bss）as follow：
The function here is to load the initialization data in ROM into RAM, but at this time the ROM address content actually points to the RAM space, and the contents of the RAM address space are all 0.
I don't know why this is the case, in the correct project the ROM address points to the ROM space, like the following:
Look forward to your reply!
Best Regards
