Re: [U-Boot] Unaligned memory accesses exception

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.

What exactly do you mean by encountered? Can you post logs? Thanks.
