Title: TFTP support in uboot for rk3288
Hi,
Can someone point me to the link for bootloader source code that has TFTP enabled. I have tried building code from http://git.denx.de/?p=u-boot/u-boot-rockchip.git;a=summary and looks like it does not generated RK3288UbootLoader_V2.19.01.bin and upgrade_tool fails flashing u-boot.bin
I could boot the board using SDcard with these images and has tftp support . But I would like to understand how to flash this bootloader to eMMC.
Tried generating RK3288UbootLoader_V2.19.01.bin from u-boot.bin using rktools but that did not help, meaning boot does not boot to uboot.

Thanks

U-Boot source code for Firefly
https://bitbucket.org/T-Firefly/ ... -boot/?at=fireprime
Use 'make rk3288_box_defconfig'
https://bitbucket.org/T-Firefly/ ... r=file-view-default
Then a normal 'make'
I can't remember all the steps.

Hi Dewet,
Could you please confirm if this uboot has GMAC support ? I mean to say does it has Ethernet support enabled?

Thanks

Gigabit Ethernet support comes from the driver in the kernel as far as I know.

You can also follow all the posts here, a user got 4.6 Linux kernel running with Slackware Linux on Firefly, maybe there are also different u-boot source code to make it boot?

yeah you are right GbE driver is in kernel. But the point I'm trying to make here is - does rockchip bootloader supports Ethernet on firefly-rk3288 ?
I would need this board support in boot loader because, I want to download kernel Image via TFTP on the board. This will enabled me the test different kernel with a line change (change in symlink) which is much much better than flashing each image at a single time. This will help folks working remotely and want to change kernel.

Thanks
