There is a bug that without CONFIG_USB_ETHER option u-boot will not load musb gadget driver and gadgets like UMS and fastboot will show this error:

Write GPT partition layout in partitions var to disk with
fastboot oem format
and then flash spl with this
fastboot flash loader1 spl/sunxi-spl.bin
and u-boot with this
fastboot flash loader2 u-boot.bin

usb ethernet stability fix https://github.com/armbian/build/pull/3763/commits/d52b67ffeeebc89f49159accb953f1ecf9352e74
r8152 will hang randomly, adding snps,xhci-trb-ent-quirk; to usbdrd3: usb@ff600000 in device tree seems to fix it
Update: No it doesnt fix it, the realtek USB Ethernet IC is just BAD and will crash and drop packets often. Just pretend it does not exist!!! My workaround was to just connect a managed switch to the onboard eth port and do some VLAN magic to seperate WAN and LAN into different virtual interfaces
Start and Size columns are in in LBA sectors. 1 LBA == 512 Bytes.

boot partiton must be LegacyBIOSBootable, contain filesystem readable by U-Boot and contain a boot.cmd script that is run on boot.
By default first-lba is at 2048 (1MB) but we need to force it to start just behind GPT structures at 64.

Since v2024.01 there is a scripts/gen_compile_commands.py that can be used to generate Compilation Database file. It's a compile_commands.json file that contains all files with all of its flags and include paths. That is enough for CLion (or other IDE's/Language Servers) to index all relevant files and provide accurate code navigation.
./scripts/gen_compile_commands.pygen_compile_commands.py has to be re-run after configuration changes.
