Hello !
Is there any way to test memory in RB433UL, it has no rs232 port, there is pins on PCB but I read it is not operational.
I tried netinstall with 5.26, 6.18, 6.20, 6.22 and 6.23rc2 versions and all act almost the same, so problem must be hardware.
All voltages are OK
After netinstall access to it via winbox and MAC , setup eth. IP and wlan card, everything looks fine and works ok.
Soft reboot pass (via winbox) or telnet, no diference but when I turn power supply off and pull it back, routerboard
becomes inaccessible, cant access to it with winbox, no ping at all.
With 6.22 routerboard reboot every about 20 second, with 6.23rc2 no reboots but not accessible any more.
Netinstall again and all looks exelent until first power OFF !
Any idea how to solve this problem or must turn it back, routerboard is still under warranty.
