Next Step: BenF V364 / V353
I couldn’t find the source, so i chnaged the dfu files.
DFU -> S-Rec -> Intel hex
srec_cat V364.s19 -Output V364_APP.HEX -Intel -Output_Block_Size 16
BenF364_LIB353.zip (49.6 KB)
Alf, looks like you have cracked it. Loaded fine and comes up as 3.64, extra featuresa all seem there, about to sit down and play.
Many thanks again to you and everyone else.
Awesome work. Did you use IAR v 6.x?
I kinda like the new loader because of easier firmware loading not requiring extra software.
Good job, alf! Glad you got it working, and that my guess about checksums/certification was proven wrong. For your information, BenF’s 3.13 version was the last open-source version, there are only minor changes to what’s in the git tree on gitorious.
I used the IAR Embedded Workbench 6.3 (6.30.7.3447)
Thanks for the info about the BenF Source code, so i will not search for the code any more.
At the moment i am glad that it works.
Yes its interesting why the hex file I posted from a zip Benf 3.1 for IAR5 I got from Google code did not work. Maybe the file name matters or maybe IAR 6 format is different. Anyways I glad Alf skills came in handy.
Great job Alf!!
Many many thanks!!!
Worked for me too. Many thanks to all supporters!

Excellent job, successfully upgraded mine too.
Thanks 
Blees you Alf…copied your files into my dso210. on repower, flash screen said BENF. I do like it better than stock. Thank you for your efforts!
Alf, greatest thanks. You are a genius! I bow to your expertise and generosity in providing these files in a format/design that is functional with the DSO201 V1 with the new boot loader.
I had a potential nightmare on my hands. I found a .hex that worked online somewhere else…but it was miss labeled and ended up being V1.1 firmware. Not very pretty…
Your two files worked perfectly for me. Up until I came across your post I could not get various .hex to work with new boot loader version.
I now have functional Ben F Firmware; LIB 3.64 APP 3.53. I’m off to go explore its features 
Hello everyone,
I came to this forum after buying a nano DSU by a Chinese vendor who seemed seriously, this is the
link diyertool.com/measuring-equi … so201.html
I have discovered that it is equipped with the updater firmeare V3.20A …
reading this tread I was able to load version benf, but I was wondering if in the future, the inability to use
the system bootloader with the program of classic St, might be a problem …
if I contact the seller, I can claim to have been cheated, because the product is not what I bought?
thanks to all

hi some one has had problem with image save?
because my dso nano with benf 3.64 (by alf) don’t save the images and showing SD Err.
I had the same problem with a Sandisk 1GB card, even though I had reformatted it with Windows it still came up “SD error”
I read the instructions for 3.64 and on page 18 it says that it is a good idea to use a program called " sdformatter " (Google for a download) I did this, loaded the program, formatted the card using this formatter program and all is now perfect. Hope this may help you.
I have same problem!
can’t update from Dfu file.
I think it made in china, thay used illegal bootloader.
What the hell is hex file, rdy file???
It must be downgrade bootloader…
but how???;;;
Following mrmutts istructions all is returned ok
thanks
Just wanted to add my thanks,
same problems, went round in circles for hours trying to work out how to upgrade. Works perfectly now!
To be honest I don’t know why the sellers on Ebay don’t ship with benF firmware, it turns it from a toy to a usable device
I have been at it for 3 days nows and the new firmware by Alf has relieved me of my misery. BenF is just great.
Great many thanks Alf.
