1721 - TFTP Upgrade Issue

Unanswered Question

hey all, i have a weird issue, the router shows that it has 32M of space but anytime we try to tftp an image, it complains that it has "(No space left on device)" we tried about 10 images but none work. i know there is a small trick somewhere. any help is appreciated. thanks a lot.


we also noticed a low voltage error message - am wondering if that is the root cause.

Hello Robert,


>> %Error: Low Programming Voltage Detected in System flash

this message appears multiple times


I'm afraid it is telling it is not able to really write or erase in this case on the flash a minimum voltage is needed and it says it is under the threshold.


It makes me think the flash can be defective or not well inserted.


I would power off ,open the device and check if it is well inserted


Hope to help

Giuseppe

Errrr ... reseat? The 1720 series router's flash are all internal DIMM/SIMM chips. It's the 1760 that has a removable compact flash slot.


I hope I'm wrong here but I believe that the unit is about to die.

the 1760 does not have a compact flash slot. anyway, let's not get off topic.
