[Solved] Linker script: block RAM for variables

Question asked by Joerg Wagner on Oct 4, 2017

How do I have to configure the linker script file to block the required space

for Ethernet buffers at 0x24000000?

STM32H743 starts with DTCM at 0x20000000, but Ethernet works in 0x24000000 only.

I want to use the RAM space around for my purpose without losing so much.

In ethernetif.c the buffers are marked with .RxDecripSection, .TxDecripSection, .RxArraySection.

I'm not a linker file specialist to make the right definitions.

Thank you for your help.
