S32K312

[shiqi_seventeen]

What syntax is required to assign a function or constant to a specified address in the S32DS environment?

I use__ Attribute__ (section (". ARM. __atx00502000")); Or__ Attribute__ (at (0x0050C000)); Define const constants or functions, but no corresponding address data appears in the generated HEX file.

Hi@shiqi_seventeen

you can check "xx.map" file in debug_flash folder.

Using the S32K312 processor, the size of the bootloader is 300k (P_FLASH0). Is there any other way to erase What is the remaining 724K space in P_FLASH0? (Do not use flash_driver mode)

Hi@shiqi_seventeen

I don’t quite understand your question, and your question is not consistent with this topic.

Please create a new topic with your new question.

Hi @Senlent，That means I am using the S32K312 processor now, the size of the bootloader is 300k (P_FLASH0). Is there any other way to erase What is the remaining 724K space in P_FLASH0? (Do not use flash_driver mode)

Hi@shiqi_seventeen

 the same FLASH module cannot be read and written at the same time to avoid RWW errors. This means that you still need to place the operations of reading and writing FLASH in different memory block, such as RAM.

Okay, I would like to ask if there are any related S32K312 routines on your end to solve such problems, that is, how to put them into RAM? This is the first time I have encountered this problem. Thank you
