106axf section `.bss' will not fit in region `SRAM_DTC', region `SRAM_DTC' overflowed by 33876 bytes

Hello,

We have an iMXRT1060 based custom board. I want to flash our application using MCU boot utility but I want it to run from SDRAM and not XIP. 

I followed the steps needed based on 

I.MX RT - How to booting to SDRAM - NXP Community

However, when I try to compile my application, I get the following error - 

Building target: imxrt1062_dualusb.axf

I tried some google search and also tried adding the following setting - 

Properties -> Managed Linker script -> Extra linker script input project 

Noncacheable .data and .bss.

But it did not help.

Can you please tell me, that if the application is big, how can I increase the SDRAM allocation? Do I only have to use DTC? Or can we use ITC or OCRAM?

Thanks,

Palak

Hi, 

I just realized that we don't have SDRAM on our custom board. And we want to use non-XIP option and run the application from SRAM. 

Can I modify the memory configuration to select the "SRAM_OC" as the primary location to download the code?

Thanks,

Palak

Hi，
Thanks for your reply.
1） Can I modify the memory configuration to select the "SRAM_OC" as the primary location to download the code?
-- Of course, and you can refer to 17. Memory Configuration and Linker Scripts in the MCUXpresso IDE User Guide to do that.
Have a great day,
TIC

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) Can you please tell me, that if the application is big, how can I increase the SDRAM allocation? Do I only have to use DTC? Or can we use ITC or OCRAM?
-- Actually, you'd better go through the I.MX RT - How to booting to SDRAM - NXP Community carefully again, in this post, it illustrates modify the memory configruation to slect the SDRAM as the primary RAM.
Have a great day,
