  1. Maybe further infos of my board; eMMC : Samsung KLM8G1WEPD-B031 PwrMgmt : X-Powers AXP803 Memory : SKhynix H5TQ4G83CFR
  2. Reading up on other topics like: and and I was wondering if maybe the default configuration for the A64 start it with a borderline high frequency. depending on the board quality it works, for others not. Combined with the fact that temperature readings seem not to work properly and as such thermal throttling not working, the system is running into a kernel panic. I furtehr noticed that the CPU is getting warmer then when using it with the Debian 4.4 image. To test this, I would like to startup the kernel with a lower frequency. Normally - if I understand correctly I would change the CPU frequency in /etc/default/cpufrequtils - but is there a way to set this on uboot?
  3. Hi I got my BPI-M64 board V1.1 up and running using the Debian 4.4 image, however I am not able to use Armbian. I tried several SD cards, and checked the power supply delivering enough juice for the board (among others I monitor the volatage on the 3.3V and 5V pins of the GPIO Pin header). For example using the Armbian_5.90_Bananapim64_Debian_buster_next_4.19.57.img with mainline kernel from https://www.armbian.com/bananapi-m64/ It starts up into u-boot fine: U-Boot 2019;04-armbian (Jul 06 2019 - 15:13:59 +0200) Allwinner Technology CPU: Allwinner A64 (SUN50I) Model: BananaPi-M64 DRAM: 2 GiB MMC: Device 'mmc@1c11000': seq 1 is in use by 'mmc@1c10000' mmc@1c0f000: 0, mmc@1c10000: 2, mmc@1c11000: 1 Loading Environment from EXT4... ** File not found /boot/boot.env ** ** Unable to read "/boot/boot.env" from mmc0:1 ** In: serial Out: vidconsole Err: vidconsole Allwinner mUSB OTG (Peripheral) Net: phy interface7 eth0: ethernet@1c30000 Warning: usb_ether using MAC address from ROM , eth1: usb_ether 230454 bytes read in 12 ms (18.3 MiB/s) starting USB...
