Hi everyone,

Now I have problem with AP 1832i boot.

Its have a boot log as below :

Booting from part1

Error, no UBI device/partition selected!

Booting failed, try boot on part2

I tried to use "tftpboot" command and boot the device by tftp .

Using the "printenv"

(RNAQ-C7) # printenv
bootcmd=bootipq
bootdelay=5
bootfile=part.bin
ethact=eth0
ipaddr=192.168.1.1

serverip=192.168.1.254

stdout=serial

Environment size: 224/65532 bytes

But now, I'm still not boot the device.

I focused one point error is "UBI"

UBI error: ubi_io_read: error -74 while reading 112640 bytes from PEB 507:4096, read 55296 bytes
ubi_io_read[188] not here
UBI error: ubi_init: cannot attach mtd2
UBI error: ubi_init: UBI error: cannot initialize UBI, error -74
UBI init error 74

Everyone have solution for this trouble ?

Thank you...

Contact Cisco TAC and organize for an RMA.

@Rich R has commented several times that the 1800 has had some problems and the best result is to just get it RMAed.
