OWON XDM1041 the unknown multimeter...

<< < (44/50) > >>

Alexel:
Hi guys.
Today I received my XDM1041. It contained firmware V3.6.0.
I read the calibration table, maybe someone will need it.
Does anyone have an OpenOCD built for Win x64 with C_DEBUGEN disabled? I want to read the full firmware, but so far there is only a computer with windows.

This is probably the hardware version not the firmware...
The firmware just displays the string from the calibration data...
There is no way to determine the OS version. :(

This is not only calibration, as well some configuration, version, serial number, etc...

Don't spend time.
This MCU (Cortex-M4) doesn't have that vulnerability.

Maybe you're right, but the PCB is marked "YW:2228", while the serial number includes this value - SN:22280222... Maybe the hardware version is included in the serial number?

Yes, you are right, I did not pay attention to the fact that the chip marking is GD32F303, not GD32F103...
At the same time, ST-Link reads the chip ID as 0x414, which corresponds to F103, and it would be logical to get 0x422 from our chip (This ID for STM32F303xB/C and STM32F358 devices).

I just did as well, couldn't pass up a $103 super low price + stackable $9 off $90 and $15 off $100; netting it for $79 ish + tax USD. But will see in a month after it arrives.

I am hoping that like the Riden RD6006 power supply, the firmware magicians can make this into something worth much, much more.

I went with the USB instead of DB9, hoping that will be the best for any future interfacing.

I got mine yesterday. Even newer than Alexel's.  AliExpress seller came through, 17 day shipping to U.S. with all the discounts, no hassle/claims of increased prices/etc.. that other sellers pull. Net cost $79+tax. Very happy.
