Remote power trouble

This log is from a dev build here out of the forum. But i give up and keep the original uboot. Yours did not work for me, i posted all logs and i want to use the image from freattab (Android), too. Everything else is working, except Power.

Where did you geht the u-boot sources? Then i can try myself.

I took the sources here

Thanks. And what did you fixed for power?

The Power-ON FW of this github works without changes.

There is another problem here that you wanted to solve yourself.

I do not want to put the changes on the net, the manufacturer should do this. The buyers of this product were fooled, the money was taken.. But the known bug was not fixed unfortunately.

And what about the Memory speed changes? Is there any special reason, that u disabled auto detection?

I have turned this off, because this feature makes absolutely no sense for devices with LPDDR3 memory .. if there is a H96pp with LPDDR4, the auto-detection would make sense, because you could use the same u-boot binary for both variants. The situation is different with H96pp devices with DDR3 or DDR4 memory, here you could use the auto-detection.

Ah ok, i see. Did you use q200 or q201 for your system? What configs did you set? My u-boot just detects 1500MB RAM, so maybe i missed something.

i've updated the LE9 last build with an Devel Update because 4K isuesses... now the box will not power on again after switch off with remote...

need a new uboot?

only q201, q200 will not work. I will do another build especially for you. Furthermore, I advise you to use the kernel with the latest changes.

For testing - try switching the box on and off without HDMI cable.

Thanks. But the config for the board would be also interesting, that i can compile by myself. You can also PM me your configuration file.

With q201 i get Addr bus failed, with DDR_TYPE set to LPDDR3@792Mhz

habe es probiert, dann geht es.

habe nun als workaround den cec treiber in LE deaktiviert, dann gehts auch mit der Remote Aus/ein ! ..??

have tryed it.. works without hdmi...

turned off CEC driver in LE, now remote off/on works ! ..??

BigMike

Thank you for your reply.

I have fixed the bug. You do not have to disable the CEC driver

Download (for LPDDR3 Devices)

u-boot@792Mhz

With this build it looks better for me. Hope i will get now freezes anymore.

EDIT: No, still crashing

Seems to do more tests now:

installed the new U-Boot with CEC, runs again !

many THX

I do not see any bugs that could be caused by the bootloader.

please do another test:

1. Erase the bootloader partition (/dev/bootloader) and turn off the box.

2. Format sdcard in FAT32 -> flash u-boot.bin.sd.bin on sdcard -> copy u-boot.bin to P1 -> insert sdcard in the box and turn it on

3. enter the following commands in the uboot terminal (gxm_q201_v1 # ...):

store erase boot
fatload mmc 0 ${loadaddr} u-boot.bin
store rom_write ${loadaddr} 0 100000
defenv
saveenv

4. Switch off the box again -> remove sdcard with u-boot.bin.sd.bin -> insert sdcard with CoreELEC -> switch on and continue testing.

Please try this dtb

Followed you steps, but still crashing with with your uboot. DTB doesnt work for me, is it for LE9? If i use q201 from coreelec image, i have no Wired Network. Dont worry, dont spend more time in my problem. I dont know, why it doesnt work on my box.

You seem to be using some application that causes the kernel crash, this has nothing to do with u-boot.

Please use dtb from here (gxm_q201_3g_gbit_phy.dtb), I made a small mistake.

Ask CE developers about the possibility of adding rgmii support to q201 dtb.
