Updating clone about lndso150

[mean00]

If i got it correctly, the question is how to upload a test fw into your device
1- are you 100% sure it is a stm32f103 ?
2- can you use instead a st link v2 over the SWD pins to flash ? I'm unsure flashing over serial is doing all that is needed.

Now regarding the issue : Usually a white screen is a sign it crashed early, it should not.
1- Did you flash the bootloader first ?
2- If you can get the serial output while it boots it would help also

Hi. yesterday I found a way to hack the original dso 150 firmware. you need to download the firmware 113-15001-120.hex from the official site and edit it in a text editor. and use KeyGenDSO150 to generate a password. and all. Now I have the latest official firmware. Here is a link to YouTube but it is in Russian. "https://www.youtube.com/watch?v=_JccGIqhuIc"

patch1 disable fake serial number check (this changes the 2 fake serial numbers in the flash to fZn6IX2r,u2uvGy8a)
change the file line number 2954
from :10B880004F205368656C6C006 5 5A6E3649583272A 9
to : 10B880004F205368656C6C006 6 5A6E3649583272A 8
change the file line number 2955
from :10B89000007 4 3275764779386100000000000000B E
to : 10B890000075 3 275764779386100000000000000B D

5. patch 2 disable the required activation code. This changes the ARM branch instruction BEQ to BNE and invert the test of the right unlock code
   change line 1616
   from :1064E000063013D 0 214C63895A1C022B62810AD8D 2
   to : 1064E000063013D12 1 4C63895A1C022B62810AD8D 1
   activation key under video. need to rename from txt to exe. try to make a video of how you perform the firmware. makes it easier to repeat.

1- are you 100% sure it is a stm32f103 ?
yes original stone
2 I didn't understand how to use stlink. The wiki has unclear instructions. rather a translation. make a video on how to flash it. I tried to flash a white screen using ch341.

I don't want to burn anything again. tired of buying new stones. ))) shoot a video on the firmware

Just in case (you can use a cheap chinese stlinkv2 clone), they work fine with openocd:

• Connect only 3 pins of the stlinkv2 to the board (they are easy to access & labeled ) : GND, SWDIO, SWCLK
• Install & run openocd (you'll have to change the path) :
  openocd -f /usr/share/openocd/scripts/interface/stlink-v2.cfg -f /usr/share/openocd/scripts/target/stm32f1x.cfg

It should display it has detected a stm32f103 and it is listening on port xxxx, normally 3333

Then start arm-none-eabi-gdb.exe

target extended-remote :3333 (it should connect to openocd)
mon halt (may not be mandatory)
file THE_ELF.elf
load
compare-sections

No need to solder anything

i think you can reflash the hex file also that way
load foo.hex
but not 100% sure

[FiusRa]

somewhere lay a Chinese clone. I'll take a look. If I find I'll try to flash it. unsubscribe about the result.
where are the files THE_ELF.elf and foo.hex

You can try the jytech 2.2 elf one, should work for you
DONT FORGET TO FLASH THE BOOTLOADER FIRST!
