22:27 <akaizen> devs: when testing uboot / kernel / os work: do you repeatedly write to sdcard from host machine => insert sdcard into target device => reboot target device

22:42 <mmind00> akaizen: I've converted most of my boards to netbooting

22:43 <akaizen> mmind00: thanks. so is it sdcard -> uboot + kernel with netboot?

22:45 <mmind00> akaizen: it depends ... my rk3188 of course can boot directly off a sd, on other boards I've just replaced the bootloader with one that always netboots (rk3368, rk3036) ... same for the coreboot on my veyron-pinky

22:46 <mmind00> akaizen: see https://github.com/mmind/u-boot-rockchip and the various *-netboot branches where I hacked up uboot ... there is probably some nicer way to do that though

22:48 <akaizen> mmind00: cool makes sense. This works if the device has eMMC or a bootloader you can flash to netboot. The problem I'm trying to solve is: if the uboot doesn't support netboot yet and/or bootloader, the only way to do development is via writing to sdcard and then attemmpting whatever you were trying to do. if that doesnt work, swap card to the host, rewrite it and attempt again

22:48 <akaizen> I was trying to see if anyone has tried sdcard emulation or something to solve this problem

22:49 <akaizen> or maybe its not a problem and fairly easy to port netboot to most if not all SBCs ?

22:49 <mmind00> akaizen: for my rk3368 (without mainline uboot at the time), I made the vendor-uboot netboot capable :-) (r88-netboot branch)

22:50 <mmind00> due to the vendor uboot being so old, this was a bit of a hassle though
