I'm not able to reproduce this

[galak]

Wondering if there are toolchain version differences?

[hakehuang]

I find this issue is because in my bootloader the 0x60000000 address is configured as device-type, hence the unaligned access will have hard fault, now I change it back then, the application works fine.
