Other Parts Discussed in Thread: SYSBIOS

Hi expet,

My customer is doing bootloader for SYSBIOS project, they need to align data in 8 byte. ALIGN(8)

Since SYSBIOS has an auto generated linker.cmd, how could we configure to make is from default alignment to ALIGN(8)?

Thanks

More specific:

1. We can not modify this file directly correct?

2. If we would like to make FLASH0 to ALIGN(8), how could we do that?

Thanks

Hi Todd,

My customer has tried to directly modify this auto generated .cmb file. It seems good but we still need to make sure this is the best practice we have.

Thanks

Hi Sheldon,

We would not recommend editing the generated linker file because their changes will be wiped out if the kernel is rebuilt. Can you attach the modified linker file though? We have a couple promising alternatives, but I want to make sure I understand exactly what they are trying to do.

Additionally, please high-light what they changed in the generated linker file.
