Dear Sirs,

I am also interested in the Flash Programmer to flash JN 5139 nodes under Linux.

I use Ubuntu 8.10 on a 64-bit machine (Mac Pro).

I tried to log in the Jennic FTP server mentioned in some thread elsewhere, but without success (wrong user/passwd ?)

Thanks,

  Sergio Ruocco

Hi,

I have done a python based programmer which works under linux, get it from http://www.teco.edu/~scholl/jenprog-1.0.tar.gz

Thanks Scholl!

I downloaded and installed it. I also installed the serial module.

However, I keep getting this error below: can you help me with that?

My system: Ubuntu 8.10 on x86_64 (Mac Pro):

 Can you enlighten a newbie as to how to put the 5148 into programming mode? I have the 5148 on an ngw100. Any assistance you can offer would be appreciated.

Thanks

Its the same method as for the 5139 - pull MISO low and reset the device (then release MISO).

 I tried to download this but the link appears to be broken .... is this still available ??

Thanks,

Here it is the patch to make JenProg support Jennic JN-5148.

The full package is available here.

Reading MAC & license works, but trying to flash a JN-5184 with your updated program, I get:

Traceback (most recent call last):
  File "/usr/local/bin/jenprog", line 93, in <module>
    bl.erase_flash()
  File "/usr/local/lib/python2.6/dist-packages/flashutils.py", line 85, in erase_flash
    assert self.talk( 0x07, 0x08 )[0] == 0, "erasing did not work"
  File "/usr/local/lib/python2.6/dist-packages/con_serial.py", line 41, in talk
    n,ans = ord(self.ser.read(1)), ""
TypeError: ord() expected a character, but string of length 0 found

Please help!
