 |
|
I'm trying to reinstall gentoo to BananaPI M2-Ultra (sunxi-linux and u-boot works) with use of Mainline U-Boot and Kernel since there is a support.
https://linux-sunxi.org/Sinovoip_Banana_Pi_M2_Ultra
But it's not booting at all - only red led signalizing power is connected and blinking LAN leds if it's connected to network.
I used these steps:
| Code: | crossdev --g 9.3.0 --b 2.33.1-r1 --l 2.30-r8 --k 4.4 -S -P -v EXTRA_ECONF="-march=armv7-a -mfpu=neon-vfpv4 -ffast-math" -t armv7a-hardfloat-linux-gnueabi
git clone --branch v2019.10 --depth 1 git://git.denx.de/u-boot.git
make CROSS_COMPILE=armv7a-hardfloat-linux-gnueabi- Bananapi_M2_Ultra_defconfig
make CROSS_COMPILE=armv7a-hardfloat-linux-gnueabi-
dd if=u-boot-sunxi-with-spl.bin of=/dev/sdX bs=1024 seek=8 |
kernel (gentoo-sources 5.7.2):
| Code: | make ARCH=arm CROSS_COMPILE=armv7a-hardfloat-linux-gnueabi- sunxi_defconfig
make ARCH=arm CROSS_COMPILE=armv7a-hardfloat-linux-gnueabi- menuconfig
make -j20 ARCH=arm CROSS_COMPILE=armv7a-hardfloat-linux-gnueabi- zImage
make -j20 ARCH=arm CROSS_COMPILE=armv7a-hardfloat-linux-gnueabi- dtbs |
boot.cmd:
| Code: | setenv bootargs console=ttyS0,115200 root=/dev/mmcblk0p2 rootwait rootfstype=f2fs panic=10
load mmc 0:1 0x43000000 sun8i-r40-bananapi-m2-ultra.dtb || load mmc 0:1 0x43000000 boot/sun8i-r40-bananapi-m2-ultra.dtb
load mmc 0:1 0x42000000 zImage || load mmc 0:1 0x42000000 boot/zImage
bootz 0x42000000 - 0x43000000 |
| Code: | | mkimage -C none -A arm -T script -d boot.cmd boot.scr |

sde2 is F2FS

I don't own a Banana PI so I can't help you with it specificaly, but I would highly recommend getting a USB to TTL adapter. It will allow you to see what's what's happening during boot and access the u-boot command line.
It cost only a few bucks but it immensely helpful - not only when playing with SBC, but with many devices like routers and NASes which have UART pins that you can connect to to diagnose issues. |

| Etal, many thanks for that. I've ordered one adapter and will give it a try. |

OK finally solved - connected USB to TTL adapter TX RX <=> RX TX
| Code: | | screen /dev/ttyUSB0 115200 |
And it printed boot process.
So nothing else than red led but it's OK.
So I compiled to kernel framebuffer support and initiated console to tty0 and HDMI connected display displays kernel boot process and login prompt.
It looked dead but it wasn't all the time it was OK but needed minimal changes in kernel and boot setup.
I hope everything I need is supported - time will show. Going to install and will see.
Thanks again for suggestion with adapter. |
