OMAP4430 Big Endian support

Masa

Does OMAP4430 support the big endian mode? I think that ARM cortex-A9 itself support big endian data mode, but I'm not sure if OMAP4430 can support it as SoC.
Also, are you preparing for a BSP for OMAP4430 big endian mode?

ARM supports only little endian mode, so OMAP does the same.

Thank you for your feedback. Cortex-A9 is ARM v7 architecture. So, it supports two different endianness. One is LE which means Little endian mode. The other is BE-8. This is the big endian mode supported by Cortex-A9. The instruction is little endian in this mode, but data is big endian.
I would like to double check if OMAP4430 support BE8 mode. Based on your BSP, it seems only LE is supported. Probably, BE-8 is not your expected mode, so the operation is not verified. Right?

Best regards,
Masa

Masa,

No, OMAP4430 does not support BE-8 mode in hardware or software.
