LPC55S69-EVK: After changing RAM size, build errors

[adriaan-pelzer]

Hi,

I'm trying to change the RAM size in the hello_world_multicore examples (core 0 and core 1). I do this in "Properties -> C/C++ Build -> MCU Settings. I'm then changing the Size property for "Ram1" from 0x11000 to 0x12000. I do this for both cores, at they share Ram1.

When I build next, I get the following errors:

cannot find libcr_c.a (lpcxpresso55s69_hello_world_cm33_core1)
cannot find libcr_eabihelpers.a (lpcxpresso55s69_hello_world_cm33_core1)
cannot find libcr_nohost_nf.a (lpcxpresso55s69_hello_world_cm33_core1)

Does anyone know why these libs are only needed after changing the RAM size, and where can I find & include them?

Thanks!

Apologies - I uploaded these straight after you posted your reply, but only now noticed that my reply never really posted (only showed as posted in my local browser).

Here we go again - let's hope it works this time!

Here are the two linked projects (core0 and core1) after trying to increase the RAM. Also find the support info attached.

Thanks!

Hi,

We’ve been able to reproduce the problem. Until we’ll have a fix in the product, please check the target architecture displayed on project settings (Properties -> C/C++ Build -> Settings -> MCU C Compiler/Assembler/Linker -> Architecture) for the project that reports build errors (the project for the second core). If you see the core as being Cortex-M7, switch it to "Cortex-M33 (No DSP)" - and make sure you'll do this for all Architecture sections in Compiler/Linker/Assembler. Then recompile.

Would you please attach the two problematic projects? I've just quickly tried the same thing and I don't see any problem. Also, please attach support info (Help => MCUXpresso IDE Save Info for Support).
