riscv-aosp's Issues

do you have the plan of Trusted Execution Environment on RISC-V chip?

seems that there is some issue when building the whole image

Wifi and Bluetooth

Anyone have the WiFI and Bluetooth drivers working on T-HEAD c910 ice hardware with Android ?

为什么买不到板子呢，没有板子，这个项目也是个废的。

fastboot: error: boot partition is smaller than boot image

Hi,

I just build the AOSP with main_2023_7_7 tagged manifest.
Following the instructions, I can flash most of the partitions with their corresponding images without problems.

Yet while flashing boot partition, it gives out the error :

fastboot: error: boot partition is smaller than boot image

And on the console, I can witness the flashing process slipped :

Besides, during the first round of U-boot flash-and-reboot, I saw GPT table was written :

Thus I am wondering shall I tweak the GPT table / size on the U-boot side ?
The boot.img I generated from the AOSP is around 32/33 megabytes :

Build failed!

hi, I tried to build and failed, error log attached, anybody else see the similar issue?

Emulator failing once it Lunched.

Hello,

I have cloned and build aosp-riscv, Currently there was 2 issues like,

when i lunch emulator it's failing and throwing an Error as follows,

$ emulator -selinux permissive -qemu -smp 2 -m 3800M -bios /home/performance-server/ghalib-khan/android/aosp-riscv/aosp-riscv/aosp/prebuilts/qemu-kernel/riscv64/ranchu/fw_jump.bin

ProbeKVM: This user doesn't have permissions to use KVM (/dev/kvm).
The KVM line in /etc/group is: [LINE_NOT_FOUND]

If the current user has KVM permissions,
the KVM line in /etc/group should end with ":" followed by your username.

If we see LINE_NOT_FOUND, the kvm group may need to be created along with permissions:
sudo groupadd -r kvm
# Then ensure /lib/udev/rules.d/50-udev-default.rules contains something like:
# KERNEL=="kvm", GROUP="kvm", MODE="0660"
# and then run:
sudo gpasswd -a $USER kvm

If we see kvm:... but no username at the end, running the following command may allow KVM access:
sudo gpasswd -a $USER kvm

You may need to log out and back in for changes to take effect.

Seems it cant be access.
Thanks a lot.

build instructions, configs and source for uboot and kernel

Hi,

While I am finding a way to workaround the partition size for #16 ,
I tried to find out the source for U-boot - - which, according to the log, writes the GPT table to flash.

Could you provide me the source, configs and build instructions for the shipped binaries, namely :

kernel and U-boot ?

Thanks in advance.
