At the moment I havn't idea what is wrong. All looks fine, except firmware flashing result for T8SG. With command line all looks similar for Devo8 and T8SG, but Devo8 firmware flashing result is OK, T8SG firmware flashing result = NOT OK.

I'm not sure that anybody can flash "devo7e-256" firmware with DeviationUpload-0.8.0.jar

Can anybody confirm it?

I guess not, that's what I mentioned in the pull request's comment :

BTW in case of the U7E, which has a filename of "deviation-devo7e-256-v5.0.0-be57e84.zip" the results would be "7e" and "256-v5.0.0-be57e84", which is not that good, I think...

It can be flashed anyway, but I think you get firmware update screen.

But if the updater thinks about an U7E, that it is a simple 7E, then it will get a wrong flash size, won't it?
Then if the fw size larger then the flash size, it should fail...

Got my new F7 but had to upload the last November nightly manually with stock 0.8 uploader. Uploading the whole zip resulted in an aborted progress bar amd a success message. Now I have a single menu line on my F7. Maybe a corrupt devo FS? Is there a way for loopback mounting? No idea about the fs type. Success seems near.

Try copy devo.fs file from archive to Tx USB drive.

Thank you, this was the missing step. Zipped the devo.fs to make it accessible in DeviationUpload but this resulted in a different md5sum. Copying it manually worked. Now I can modify the devo.fs file with buildfs.exe only in wine (wineconsole --backend=user cmd) which is super inconvenient

.
Update: buildfs.py works faster.
But I guess devofs will never make it into the kernel tree or fuse. I added DSMX, J6Pro, PPM and USBHID protocol. Would be great to have language modules.
The good thing is it all worked with a free OS and DeviationUpload 0.8. Great stuff.

Last edit: 07 Jan 2018 12:52 by Schugy. Reason: using buildfs.py now

Did you make any progress on this issue? I'm a little annoyed that I have to boot into Windows to flash my jumpers...

Vlad, can you check your devices serial numbers? Maybe we can use this to differentiate between different versions in the uploader:
This is what I get for my Jumper T8SG:

STM32 DFU:
Product ID: 0xdf11
Vendor ID: 0x0483  (STMicroelectronics)
Version: 2.00
Serial Number: DEVO-7E 㐀げ仿⌵㜅Q

And this is the result for the Jumper T8SG V2 plus:

STM32 DFU:
Product ID: 0xdf11
Vendor ID: 0x0483  (STMicroelectronics)
Version: 2.00
Serial Number: DEVO-7E „ÄÄ·âç‰áøÌππ·Ä∏„åÖC

I do not think it is related to the id read from the device, as the only difference in the 256 boot loader is two bytes almost at the end - not where the device is identified from. I rather suspect it has to do with the flashing and page addressing, as 256k and higher chips are high density devices with 256 pages of 2 Kbyte vs 128 pages of 1 kbyte. ~~I don't know how this relates to the sector overriding stored in Transmitter.yml or the flashing process itself, but I think~~ this is where you could start looking.

Taking a closer look, this could actually be the reason:
The patched firmware for 256k wrongly reports Interface 0 as 1k, while it should be 2k (see devo8 output)

Device  Interface    Start        End    Size   Count
Devo 7e
                0 08003000   0803ffff    1024   244
                1 00000000   0001ffff    4096   32
                1 00020000   001fffff   65536   30

edit:
Indeed this was the problem! Overriding interface 0 in Transmitter.yml let me successfully flash the t8sg dfu file!

matchRules:
    - "DEVO-7E.*"
    - ".*devo7e.*"
    - "7e"
    - "t8sg"
    - ".*t8sg.*"
overrideSectors:
    - iface: 0
      remove: true
      add:
       - start:     0x8003000
         end:       0x803ffff
         size:      0x800
         count:     128
    - iface: 2
      remove: true
    - iface: 1
      remove: true
      add:
        - start:    0
          end:      0x1FFFF
          size:     0x1000
          count:    32
        - start:    0x20000
          end:      0x1FFFFF
          size:     0x10000
          count:    30

Now we need to overwrite sectors for iface 0 when a firmware >128k in size is selected (devo256 or t8sg*) and maybe issue a warning to ask the user to verify (s)he is using a transmitter other than a regular devo7e.

I think "count" has to be 122 (122*2K = 244K), size without bootloader (16K). Devo8 "count" = 120.

Yes you're right, count has to be 122 with 12k bootloader in devo7e and its variants.
I'll try to modify the uploader to read out the changed bootloader bytes to automatically switch to the 256 settings if applicable, as that would be the most foolproof. Haven't done any Java in 15 years, so please be patient

Probably it can be solved without overriding interface 0, by modifying class DfuMemory:

...
                if (m.matches()) {
                    int count = Integer.parseInt(m.group(1));
                    int size  = Integer.parseInt(m.group(2));
                    if (m.group(3).equals("K")) {
                        size = size * 1024;
                    } else if (m.group(3).equals("M")) {
                        size = size * 1024 * 1024;
                    }
                    if (count == 244) {
                        count = 122;
                        size = size * 2;
                    }
...

I still prefer adding an entry in transmitter.yml for „Devo7e-256/T8SG/T8SG plus/IR8M“ so escpecially the users of the latter transceivers do not get confused by the display of devo7e as the identified transmitter. I guess doing the type detection by the flash count is just fine for now. Would you mind pushing your changes to github together with a pr to the upstream repo for further refinements?

At any case bootloader has "DEVO-7E" as identifier and DfuSe also display "DEVO-7E" for "Devo7e-256/T8SG/T8SG V2 Plus/IR8M".
