8K alignment in vector table

[DSRnathan]

Hello developers,
What is meant by 8K alighment in settiing the address of the vector table.


Kindly help me in this regard.

Thank you all for your support.

The BIV should be double word aligned. The 8K is a space reservation if you assume 32 bytes per entry and 256 entries (8192). You can also set the VSS=1 such that the full vector table space would only consume 2k.

Usually you define the BIV value and space in the lsl file and then take the linker symbol for this and use it in your startup code. Look at the base project in Bifaces and see the file ifx_Ssw_Tc0.c for an example.
