Hi All,

I want to allocate array[2000][160] on STM32H743I_Eval using STM32CubeMx.

Is it possible to allocate stack of this size?

Regards,

Manish

And what type is this?

Probably inadvisable, why do you need to do this as a local/auto variable? Could you use the heap? Preferable not to have the Stack on external memory. The stack or heap can be the entirety of the available memory if you want to do that.

In Keil Heap and Stack sizes are set in startup_stm32xyz.s

Thanks Clive.

Variable is 'char' type. Though, I could have chosen heap but i want to know that

1. How can we increase our stack size if there is need to do it ?

2. How can we segregate and allocate size to 'stack' , 'heap' etc. Basically, How can

   we design our own memory layout in linker script file.

Regards,

Manish

Usually done within the toolchain.

Stack size and heap size are supposedly project properties, not part of the source code itself.
