I am currently busy preparing the release, all checks will be after the release.
 
 

> New ver 20220622 for D1 (Nezha Lichee RV Mango MQ pro etc) and StarFive V1 (u740)
This one, i've tested CLI only image - Armbian_22.08.0-trunk_Nezha_jammy_current_5.19.0.img.xz ( https://disk.yandex.ru/d/da8qJ8wyE1hhcQ/Nezha_D1/ArmbianTV/20220622/Armbian_22.08.0-trunk_Nezha_jammy_current_5.19.0.img.xz?pane=file-info )
Is there a way to determine which image that was from burned SD card content or booted Mango? (as i`m not sure that this is the only image that had RVV support). But i`m pretty sure it was june-july image, corresponding to your initial bring-up efforts for Mango PI.
Thanks!
 
P.S. I will check new images again with another sdcard to provide thorough report on which images boot and have "v" in "isa" and which do not
 
Image that has RVV outputs following when queried:
 
> msomeone@nezha:~$ uname -a
> Linux nezha 6.1.0-rc3-d1 #trunk Fri Jan 13 08:21:24 UTC 2023 riscv64 GNU/Linux
> msomeone@nezha:~$ cat /proc/cpuinfo
> processor       : 0
> hart                 : 0
> isa                   : rv64imafdcv
> mmu              : sv39
> uarch             : thead,c906
> mvendorid    : 0x5b7
> marchid         : 0x0
> mimpid          : 0x0
 

Specify the exact name of the image where there is support.

@gounthar, notice the "v"  character missing in your output, so it means that that particular image does not detect vector extension.
isa : rv64imafdc For MangoPI MQ(PRO) - The thing is that there were several builds that successfully detected RVV extemsion ( RVV v0.7 ) present on c906 CPU, and there were builds that do not.  I`m wandering what has changed in those images, that prevents "v" appearing in "isa" line of /proc/cpuinfo? And how to enable it again?

Which of https://disk.yandex.ru/d/da8qJ8wyE1hhcQ/Nezha_D1/ArmbianTV images will support MangoPi MQ PRO and still have vector extension (RVV) present in /proc/cpuinfo ("rv64imafdcv") ?
Please advise,
thanks!
