Hello all,
I'm bringing up U-Boot for an iMX6UL board, and I've encountered unaligned memory accesses exceptions while I was trying to test the ETH commands (e.g., 'ping').
After investigation, I found out that the iMX6UL processor traps unaligned memory accesses by default. As a workaround, I disabled theses checks, hoping for negligible performance loss.
I'm wondering if it is a bad idea to disable unaligned memory accesses during the U-Boot execution, regarding performance issues or other drawbacks at the kernel level.
Thanks for your suggestions. Best regards, Fernando A. E.
