Filesystem corrupted

yellobello

Hi!

I get filesystem corrupted error, and I already tried formating the drive through usb with different operating systems with no success.

I only see a change to ressurect my DSO203 by re flashing everything through serial.
A better idea?

On bootup it says FatFS fail

Hi, would you tell me what your DSO203's DFU version is? Can you enter DFU mode after upgarded fail? May I know which firmware you were trying to upgrade?

It says "Device Firmware Upgrade V3.12C" when turning on during play button pressed.
Thank you!

Hello,
It works normally if it says"Device Firmware Upgrade V3.12C" when turning on during playbutton pressed as it entered to the DFU mode.So, you just need turn on your DS203 again without press any buttons andsee if it works ok?If it can not work, can you enter to the DFU mode and reinstall thefollowing firmware? 203S1_64.zip (21.79 KB, 下载次数: 3024)

Ok, here comes the Problem:

I really can enter DFU mode , the display shows : "Device Firmware Upgrade 3.12C please copy hex or bin file to the DFU virtual usb disk"  BUT  I am unable to copy any file to the disk
since I can not open the disk on my computer. I tried Windwos 7, Windows 10, Ubuntu and Mac OSX and none of them is able to open the disk that appears when entering dfu mode.
The filesystem is corrupted, i can not even format the disk, I get errors for whatever I try...

What to do now? I can´t copy your files since I can not access the USB DFU disk

Itmust work on Windows7 or XP only since your device DFU is version3.12. (BTW,your device DFU is V3.12,right?)

Makesure you did the following steps correctly:
1.      Connect the DS203 to your PC with a mini USB cable.
2.      Hold down the Run ">II" button while turning on DS203.
3.      It is now in firmware upgrade mode, and a USB disk should appear on yourPC.**Please confirmif a removable disk named “DFU V3_10_D” will appear on your PC? If not, pls tryto another mini USB cable or another USB port until the DS203 can be connectedto your PC.
4.      Copy the firmware to the root directory of this disk.
5.      Restart DS203 and the firmware is upgraded.

Hello!

It´s me again!
I went to see a friend who has windows 7 on his notebook.
when inserting the DSO the computer finds a drive which has no name. When clicking on it, it says that the disk can not be accessed.
When trying to format the disk (which has no name) the format program exits, saying that formatting does not work with this disk. I tried it hundreds of times in the meanwhile. Off course my cables are OK.
It does not work with linux, it does not work with my mac and it  does not work with neither windows 10, 8, and 7 .
When booting the normal oscilloscope app with no buttons pushed on startup it also says : "FatFS fail"
Also, saving and loading in the oscilloscope does not work.  
Can it really be that my internal disk is corrupted? Or at least it is somehow wrong formatted? I don´t believe that the flash memory has a hardware failure since the oscilloscope just works fine.
How is the internal flash divided/partitioned?  There must be the bootloader (with DFU), then the SYS and then the 8mb/2mb internal memory... hw 2.72 has 8mb, right?  
There must be a problem with the user space disk. Can you imagine this?

By the way.. I received today your TS100 soldering iron! It is a fantastic little device !! Great!

DFU is 3.12C, I forgot!
