Hi You have done the hard part That problem is usually the sign of a problem when saving stuff to the flash 1- What is the complete reference of the...

1- Ok, assuming it's a guenuine STMF103CxT6 it should have 128 kB (but claiming it has only 64 kB) The "Flash loader Demonstrator" is using serial or swd ? There...

Could you try the attached binary ? It skips calibration check, so you'll have garbage on screen but to check everything else works [](url [lnDSO_nocal.zip](https://github.com/mean00/lnDSO150/files/9770900/lnDSO_nocal.zip)

If it fails at the first calibration step (i.e. AC or DC) and not a the end, it's not the flash but rather the ADC If the test binary works...

Ok so in "normal" mode the ADC is working The display is gibberish because without calibration the values are out of scale Can you get the serial output when you...

If you are willing to help me, i can try to find out what's going wrong by providing test firmwares, will probably take a few steps

Does this work ?, it will go to calibration at start (Trying to pindown the issue) [nocal_mark2.zip](https://github.com/mean00/lnDSO150/files/9779083/nocal_mark2.zip)

Next : This is the expected output Setting new GainRange=0 Starting ADC... Ending ADC... Range : 0 val=2062 My guess is you will only have Starting ADC... [cal3.zip](https://github.com/mean00/lnDSO150/files/9782698/cal3.zip)

Another one to test, i'm not expecting it to work but i fixed a bug, mayb.... A couple of questions : - When you switch the AC/DC button, does the...
