| Agilent 34461A corrupted flash |

I tried connecting through a network switch and also through my wireless router LAN connections and cannot make a connection to the 34461a. Front panel USB does not work either. Rear USB I don't know as boot log is showing I have 1 USB connection but it seems like it's not working. Not recoginized if I plug it into my laptop USB. So, this looks like if I need to use Ymodem if I want to attempt installing a new kernal. |

mmm seems the problems levels have increased some talked about spear mcu damages, flash corruption, some about some voltage regulators who failed in the mcu section ... dang it would need a working one and probe into many places to get voltages, data points. memory dumps etc ... well done keysight well done :-- |

Tried to convert Nk.bin to nk.nb0 using viewbin.exe to get start and length which did not work giving error "Missing B000FF) Not a BIN file". Then was going to use cvrtbin.exe afterwards but assuming that won't work either. What's the reason for this? I'm trying these utilities because I don't want to have to install another programming environment to do the conversion or extraction of nk.nb0. analogRF, you mentioned you have a good nk.nb0 file you can share? It would be greatly appreciated. update... So, i decompresses nk.bin, used a small Russian made utility to create the nk.nb0 file. Then I uploaded it via Tera Term Y modem using loady waited the long 40 minutes. After it was done I ran "go 0x00320000" and nothing happened. :(. Could be something wrong I did maybe like not have a good nk.nb0 file. Tried bootm also after another 40 minutes got wrong image format error. |

The FW in your device right now is 2.17. if you use another bin file it wont work but where did you load the file in the memory? I am curious how did you come up with "go 0x00320000"? you have to load it into 0x0361000 ("loady 0x0361000 115200" if you want to use ymodem) and then after finished loading with no errors use "go 0x00362000" to boot but like I said, you can use tftp if you set up a tftp server and put the nk.nb0 file in the shared directoy and then use the dhcp command at p510> prompt. believe me it will connect to ethernet and will get an IP instantly and download the file. Use the same address 0x0361000 for downloading the bin file into memory. still I am puzzled why your device thinks there is an ethernet cable connected when there is none but who knows... let's see if it boots |

Thanks, very much appreciated, I was looking at past posts and looked like it was mentioned to load the nk.nb0 file at 0x00320000. Anyway, thanks for pointing out my mistake because it looks like I was doing this all wrong. I think I tried DHCP command and didn't do anything but I'll try it again and see if it gets working. Really, thanks for the help. At work so, won't be able to try anything till tonight EST. |
