EDGE-V Boot Sequence & U-Boot

Spikerguy · March 17, 2020, 10:52am

So Edge-V Can only boot from eMMC or Sd Card. Is that right ?

Spikerguy · March 18, 2020, 9:26pm

@numbqq
I cannot acess the device over uart.
I tried different baudrate 115200, 1500000, 8250 (found in libreelec extlinux.conf)
Libreelec boots give from sd card but it doesn’t have a uboot binaries inside for reuse.
Other method i can do is basic the uboot from existing libreelec but how many MB is needed from the existing img?

I tried creating Manjaro img using mainline uboot but it doesn’t boot. Then i tried uboot from. Armbian img and that gives me no display which means uboot is recognized but its getting stuck somewhere so to find it i need uart to work.
If you have bsp or mainline pre built uboot then please share it with me for testing.

Thanks.

The baudrate should be: 1500000

Check docs here: https://docs.khadas.com/edge/SetupSerialTool.html

You can check the prebuild images here:

I had trouble with a P2303(EOL) based serial tool on Windows 10, could not achieve the required baud rate on that tool. Same tool worked fine on Linux. Of course, check TX, RX connections, easy to get them switched.

Spikerguy · March 19, 2020, 3:50am

Thanks for the links but i am aware of them, my question is about pre built uboot link.

Ive tried on linux only and I am able to use my uart for all other sbcs with 1500000 baudrate just fine only issue is on edge-v.

Ill try another one and see if that works

balbes150 · March 20, 2020, 7:18am

No, that 's not true.
EDGE-V with the correct u-boot in eMMC, runs systems perfectly from USB. I have been using this option for a long time on all rk3399 and can easily start any system with USB. You only once need an SD card to install an Armbian or Libreelec system in eMMC that supports USB startup .

Spikerguy · March 20, 2020, 7:29am

Hi @balbes150
Can you point me to the write uboot for edge-v?
Which can boot from emmc, sd and usb?

Spikerguy · March 20, 2020, 7:30am

Tried a different uart usb and now I can read the uboot logs. Now next is to get a working uboot for it.

Thanks

balbes150 · March 20, 2020, 7:31am

When writing to an SD card, you must use two commands to save the MBR.

Spikerguy · March 20, 2020, 7:33am

I just tried this few mins ago and facing error.

I will try the one from this link. Thanks

Do we need any boot script for rk3399?

balbes150 · March 20, 2020, 7:36am

These versions are designed to use the system settings used by DTB and startup parameters ( uEnv file.txt), which is used in Armbian and Libreelec.

balbes150 · March 20, 2020, 7:39am

Show the launch log of the latest Armbian versions (20.05) and the log from LE 20200319

Spikerguy · March 20, 2020, 7:50am

@balbes150
I flashed Armbian 20.05 from the above link
using
sudo dd if=u-boot-rk3399-khadas-edge.img of=/dev/mmcblk0 seek=16384 conv=notrunc
Log here
I think I need the right sector information to flash is correctly.

balbes150 · March 20, 2020, 7:54am

You are writing u-boot incorrectly. Write the Armbian image to the SD card using the program (not the DD command ). Configure the DTB. Show the result of running u-boot in the Armbian system.

No I have 4 gb version.

Spikerguy · March 20, 2020, 7:59am

Which program?

I will write armbian img to an sd and share the logs in few mins.

Libreelec works fine without any issue.
