AR-300M broken? No nand flash


#1

On my new AR-300M with updated uboot no NAND flash is shown. Could it be the devicde is broken?

AR300M-EXT booting to NOR only - due to broken NAND?

Furthermore “run nlf” is missing, so I have no chance to flash NAND Firmware:

#3

@alpha1974, is it an AR300M-Lite? The NAND is not installed in them.


#4

No no, it´s for sure an AR300-M (not Lite-Version). It seems that U-Boot 1.1.4-g36de7573 doesn´t support my NAND flash.


#5

@alpha1974 Did you update the uboot or did it come that way?

I read on here somewhere the old uboot can be downloaded…

The question is, do you need the NAND?

I have an AR300-M booting NOR with LEDE 170104, luci, uhttpd, lighttpd, loads of php7 modules, usb storage packages, minidlna, and various other packages and there is still 8MB of free space :slight_smile:


#6

Same problem here. When it arrived, I sure had the 128 MB flash.

Tried several different U-Boot (February, March, May), but now it doesn’t even show the NAND at boot:

Normally there would be the NAND showing up.

ath> nand erase

 

no devices available

NAND erase shows “no devices available”. So I can’t flash the NAND, not with U-Boot and not with TFTP / UART.

What parameters / env are missing?!


#7

Is your antennas black? On latest AR-300M nand module is optional!


#8

As I said i definitely have the 128 MB NAND flash. It showed up before I updated the UBoot.


#9

Slightly off-topic but why did you start fiddling with you Uboot in the first place?


#10

In order to make the switch work for choosing the boot device (NAND/NOR).


#11

Hi

The attachment is the AR300M uboot.It contains the nand drivers,you can have a tyr

 


#12

Thanks, I flashed it, but still no NAND there. btw i got two white antennas.
