Takuya Miyashita 072890c1bf arch/arm/src/armv7-m/arm_vectors.c : Add the address alignment. ... Add the address alignment to keep the constraint of ARMv7-M architecture same as RAM vector. ARMv7-M architecture describes the vector table address alignment as following. The Vector table must be naturally aligned to a power of two whose alignment value is greater than or equal to (Number of Exceptions supported x 4), with a minimum alignment of 128 bytes. I wonder why the implementation of arm_vectors.c does not follow this constraint of address alignment about ARMv7-M architecture. Although RAM vector is taken care about it. I think, as the result it was done by linker script on each board. At our system, NuttX will be started by bootloader. To fix the address of entry point(__start) I set the address of entry point to beginning of binary, so the beginning of binary is not a vector table. At this case, keeping the address alignment constraint of arm_vectors.c is needed.		2024-06-05 21:47:57 +08:00
