Hangs on first calibration screen --processing--

[ShaviTF]

The whole procedure has apparently gone well, but when I start the device for the first time, it asks me to place the probe to ground, then to put it in DC mode and when I click ok it indicates --processing-- and it hangs... Any suggestion?

And please check the quartz is a 8Mhz one, that 's probably the case

My imitation dso150 stays at setting input to DC, no button responds; Regardless of short press or long press; I use the serial port to download the firmware and it is probably successful; The mcu is stm32f103c8t6 programmed according to 128k and the verification is successful; Tomorrow I will test the above firmware and record the serial port information; Thanks a lot for your work, sorry for my weird english because I'm using google translate;

If the buttons are not working it is a hint you may have the wrong FW non fnirsi fw on a fnirsi board or fnisi fw on a non fnirsi board

Same for AC/DC selection

Use ST-LINK Utility to re-download bootloader_2.2.bin and lnDSO_JYETECH_2.2.bin, same as yesterday, get some serial port output: Setuping up DSO... 0: R=18 overSampling=0 1: R=36 overSampling=0 2: R=90 overSampling=0 3: R=180 overSampling=0 4: R=360 overSampling=0 5: R=900 overSampling=0 6: R=1800 overSampling=0 7: R=3600 overSampling=0 8: R=9000 overSampling=0 9: R=18000 overSampling=0 10: R=36000 overSampling=0 11: R=90000 overSampling=0 Starting sanity Check Check ok read Offset =0x4 Starting DSO...

I hit the ok button here

Adc : Asked for fq=1000 got fq=1000 intDiv:1 intFrac=6464

Does not respond to any keystrokes after that I want to test cal9.elf, but I don't know how to convert it into a bin file

Has there been any progress on this? I'm having the same issues :(

What DSO are you using ? What is the marking on the chip ? STM32F10x or CH32Fxx ? the current assumption is the board is using a not so compatible clone of the STM32F103

[MarkedOne]

It's the STM32F103 (STM32F103CBT6). I managed to get it working again on the Jyetech 113-15001-120 firmware with the patch and activation code and all previous versions after posting here but lnDSO150 still looks appealing 😄

Fair assumption. If there's anything I can share to help, let me know.
