Add support Novatek NT98513 #262
Description
I connected to UART of vendor firmware with Novatek NT98513.
root@NVTEVM:/tmp$ uname -a
Linux NVTEVM 4.1.0 #1 PREEMPT Fri Sep 4 14:18:00 CST 2020 mips GNU/Linux
So I downloaded the latest ipctool-mips32 and run it.
root@NVTEVM:/tmp$ ./ipctool-mips32
ipctool: SoC not recognised, no hardware report possible.
no UART0 entry in /proc/iomem
no vendor matches /proc/cpuinfo: Novatek
Run it as root on the camera. If this is an IP camera or DVR,
please report the SoC with the output of
'cat /proc/cpuinfo; cat /proc/iomem; dmesg | head -40' at
https://github.com/OpenIPC/ipctool/issues

I'd like to add support of ipctool for this SoC. Ready for any tests if needed.

novatek: detect NA51023 (NT9851x) on mips -- chip ID 0x6E19 at 0xC001…
widgetii commentedon Nov 3, 2026
Thanks for the detailed report. #263 adds NA51023 detection on mips: the Novatek row was compiled for ARM only, and this die's chip ID (0x6E19 at
0xC00100F0, taken from the NA51023 BSP) is now read when the kernel has no/proc/nvt_info.Once the rolling
latestrelease rebuilds (a few minutes after the merge), could you downloadipctool-mips32from https://github.com/OpenIPC/ipctool/releases/tag/latest, run it with no arguments, and post the full output together with:That confirms the chip ID and shows whether sensor detection (your OS05A10) and the memory figures can work on this kernel. The report will name the chip NA51023, because the same ID covers NT96672 and the NT9851x parts.

Thank you for quick response. Below required commands output:

Thanks for testing.
devmem 0xC00100F0=0x6E190000confirms the NA51023 chip ID, and detection works, so I'm closing this as fixed by #263.The sensor isn't reported because this kernel has no
/dev/i2c*, so ipctool has no bus to probe the OS05A10 on. If you'd like that too, please open a new issue with the output ofls /dev; cat /proc/devices; ls /sys/class/i2c-adapter /proc/nvt_info/*.
