I have OpenWrt 21.02.1 installed on a new U7623 router. I have the unusual problem that the kernel is reporting there is double the amount of actual RAM present.
dmesg initially reports the correct amount of RAM:
[ 0.000000] OF: fdt: Machine model: UniElec U7623-02 eMMC (512M RAM)
But both free and cat /proc/meminfo report that there is actually 1024MB present:
# free
total used free shared buff/cache available
Mem: 1028520 38204 957388 1124 32928 937468
Swap: 0 0 0
# cat /proc/meminfo
MemTotal: 1028520 kB
...
The device was upgraded from the vendor OpenWrt 14 to 21.02.1 first by a sysupgrade to the legacy image, then by a sysupgrade to the full image. For good measure the MediaTek flash software was also used to flash over USB UART.
I am looking at the board, and there are physically two 128MB x 16 bit chips mounted on it (NTCC128M16JR-EK x 2).
Linux is convinced enough that the memory is real that it will try and use it, which causes the device to reboot.
Full dmesg and /proc/meminfo to follow:
