Whats a Parameter file?

Orion · Posted at 8/5/2017 04:53:59

Im new to embeded linux so this might be an obvious question, but where is the parameter file that is mentioned in the second part of this guide : http://wiki.t-firefly.com/index. ... 399/Build_kernel/en
it seems to be important to flashing the device in the correct locations but i cant seem to find it anywhere in the kernel source files.

also i believe linux requires uboot to start it, would that mean i would have to flash uboot at 0x00000 for example and the kernel at 0x12345(end of uboot)?

the parameter file did not exist in kernel source .
you can unpack our firmware to get it

But that page is about RK3288, and the question was about RK3399. Many parameters should be different, and it's quite tricky to get them all right. It would be appreciated if you could provide a parameter file on page http://wiki.t-firefly.com/index. ... 399/Build_kernel/en that works with the kernel and the board that is actually described on that page. The instructions are really not complete without it.

You can get your current parameters file using rkflashtool:

rkflashtool p

Copy the code

Should return something like:
