Notes about some useful Yocto debugging commands

Last and this weekend I spend some time on mounting NFS rootfs on STM32MP1… There are some PHY driver issues and permission issues troubled me a lot…

Today I just managed to boot kernel via TFTP on STM32MP1 board but steps I go through are quite different with i.MX8. Thus, I think there is a necessity to have a short note about this 🖋

It specifies that a member field has the smallest possible alignment. That is, one byte for a variable field, and one bit for a bitfield, unless you specify a larger value with the aligned attribute.

Recently I start to evaluate the feasibility of porting one old C++ Qt4 project to PyQt5 since Python is more friendly for some engineers.
