#71 Wrong RAM amount in linker script in STM32F429_439xx Project Template

[AlexX]

Wrong RAM amount in linker script file "mem.ld" in STM32F429_439xx Project Template. Specified 128K, while all STM32F429_439 devices have 192K RAM (+ 64K CCM).

/projectname/ldscripts/mem.ld:

...
MEMORY
{
  RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K
...

should be

...
  RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 192K
...

that's correct, I'll try to find a fix for the template plug-in.

I analysed the F4 family and changed the template to generate different mem.ld files according to RAM size (64+0, 128+64, 192+64).

The beta version is available from:

Could you give it a try?

hi Alex,

I just updated the stm32f4 template to the latest cube drivers.

could you test it and provide feedback in the 'Beta versions' traceker?
