I'm using a STM32H753 with external RAM. We were using it for LCD framebuffer. Now we are trying to migrate the stack and heap to the external RAM, when we run the code, getting hardfault on lines where std::array is declared. Any idea on how to debu...

bl __libc_init_array executes without any issues and enters main() too. if we have the following code, std::array<uint8_t, 12> Buff{};std::pmr::monotonic_buffer_resource resource( Buff.data(), Buff.size(), std::pmr::null_memory_resource());The ...

This is our memory map, the frame buffer sits in SDRAM and the bss, stack, heap sits in SDRAMEXMEMORY{ DTCMRAM (rwx) : ORIGIN = 0x20000000, LENGTH = 128K ITCMRAM (rwx) : ORIGIN = 0x00000000, LENGTH = 64K RAM_D1 (rwx) : OR...

Initially we were using Internal RAM only for the stack and heap, but features kept on added and we ran out of internal memory, hence we are trying to move to external ram.

That already taken care of, we followed the example given in the cubemx, initialized the FMC in the systeminit. We are using freertos all the tasks are up, what is strange is the hardfault occurs on the std:array declaration line in one of the task.
