What are the U-boot debugging practices in the sources?

Question

linux

Tell me what tools you use for convenient debugging of U-Boot (for example, for ARM). To understand the organization of the code, the principles of operation of U-boot, I want to be like a debugger, look at the variables.
In order not to bother with JTAG and the target platform, I see it like this: qemu + eclipse + gdb. In qemu, load u-boot and "debug". But that's in theory. But in practice, to assemble all this, you need to collect information in parts on the Internet.
Maybe there is a site, a project that solves the problem? The opinion of people in the "topic" is interesting. Who can share useful links, experience?

Answer 1

in practice, to assemble all this, you need to collect information in parts on the Internet.

in practice, you need to find a board that is supported by both U-Boot and QEMU. Collect U-Boot for it. Among the build results there will be an ELF file, load it into QEMU with the -kernel option. Use the -s -S options to enable gdbserver. Run gdb with this ELF and join QEMU.
Where is the difficulty?
