| 10:47 | Ke> | ok, now I get at least the default kernel to boot |
| 11:00 | Ke> | heh |
| 11:01 | Ke> | mcbin never boots on first cold boot |
| 11:01 | Ke> | or my unit at least |
| 11:04 | Ke> | damnit, it seems there is some magic that the default autoboot does that my sdboot does not do |
| 11:27 | Ke> | I guess the next thing to try is to make sure, I have strong enough power source, current one only should give 1.5V |
| 11:28 | Ke> | 1.5A |
| 12:46 | jnettlet[m]> | 1.5A is just enough for the base system. It is a 15 watt board generally. |
| 12:48 | Ke> | I guess I need to keep debugging then |
| 12:52 | Ke> | at least it seems that no bootloader stage is zeroing the dram, so there's a lot of state that can do nasties |
| 13:03 | jnettlet[m]> | Ke: I have been building the u-boot with gcc 6.3...however with mainline u-boot for the iMX6 I have found a bug where it is corrupting memory somehow, going back to gcc 4.9.x resolved the issue. |
| 13:03 | jnettlet[m]> | I need to spend a day this week bisecting to figure out where things are going haywire. |
| 13:45 | topi`> | Ke: I have also seen the freeze after mv-ddr is finished. I don't remember what kind of tricks I did to get it to boot successfully |
| 13:45 | topi`> | I was running DDR at 2100mhz |
| 13:46 | topi`> | but it was not about that |
| 13:46 | topi`> | I think I ditched a part of the Secure Firmware that was needed for the cpufreq stuff to work |
| 13:47 | topi`> | after that, I could once more boot the machine, but cpufreq stuff wouldn't work (even though the Kernel had them) |
| 13:47 | topi`> | I hope this helps |
| 13:47 | topi`> | I can't remember which part of the ATF was responsible for the cpufreq stuff |
| 13:50 | jnettlet[m]> | topi`: yeah that firmware is required to initialize the power management sub system. |
| 13:50 | jnettlet[m]> | if that is causing problems then I will open a bug with Marvell |
| 19:27 | flips> | vpeter: Left it for some hours, it went from black/blank screen to this: https://imgur.com/a/vIxYQ |
| 19:29 | vpeter> | Try fresh install. Maybe update didn't go well. |
| 19:30 | flips> | Will do, I guess I should be able to restore from backup afterwards :) |
| 19:34 | vpeter> | Don't you have 2 sd cards? :D |
| 19:57 | flips> | I do, I have many ... just wanted to try the upgrade, from the living room without serial console etc ;) I was referring to the KODI/*Elec interface GUI backup :) |
| 20:09 | vpeter> | I understand. And upgrade should work. |
| 20:23 | flips> | Maybe it was most tested with 7.x-->8.x? :) |
| 20:26 | vpeter> | There are not much imx6 users so it was not much tested in field. |
| 21:27 | flips> | So ... I'm part of the few, the elite, the Chosen Ones? ;-p |
