AM62P: APP image too large when pack using elf2rprc tools

Hi,

What is the size of your elf file and appimage file currently and how much size reduction do you expect for your appimage? 

Pu Jia said:

Can we support to pack the Motololar S19 file to rprc /appimage file

We don't have any tools in MCU+SDK to support this.

One more question is ,  if we have our own PCB which didn't want to seperate the emmc to boot area/ UDA, how can I do this? 

Please create a separate E2E for this query.

Best Regards,

Meet.

Hello TI team

My application abs/elf file size is about 24MB. the elf to s19 it's about 4M. it's too large for us.

2.I will create a new query.

The output RPRC file should be much smaller in size than this, could you let me know the size for the RPRC image generated.

Hello TI team

This's the abs/ rprc infomation:

We can't reduce the size for the RPRC file, you will have to try to reduce the size of .elf file only. You have not shared the size of the .elf/.out file, I only see the size for the RPRC file. What is the compiler optimization you are using? You can use -Os/release build to reduce the size to some extent.

Hello Thaker

It's the same issue in which in AM62P: APP image generation / run issue. - Processors forum - Processors - TI E2E support forums

1. I edit a makefile to generate a elf file to rprc, but the size became larger.... now I edit a another makefile which come from DDR demo in MCU, now we successfully to generate an appimage and bootloader can load.

2. bootloader cannot load the mcu r5 appimage.

So we are in here: edit the bootloader code to remove A53 app image load to let app run with error in that question. Our team didn't know the link parameter  to let the bootloader run it 

Hi Pu Jia,

The concerned expert is out of office. Please expect a delay in response.

Thanking you

Yes, you can close it
