Good afternoon!
Part1. Please tell me, I’m experimenting with the STM32F1 using CW Husky. I have encountered multiple “Fail to detect chip etc” errors. 15 such errors, 1 detection. For 3-5 detections, 1-2 successful failures with data acquisition. I looked at the oscilloscope - my IO2 line stretches down synchronously with the +3.3v side connector. I guess it’s because of this behavior of the power line that I have errors.
Part2. I connect the microcontroller directly to Husky. io1 - tx, io2 - rx, gnd-gnd, crowbar - to the power supply of the controller, 3.3v husky through 10 ohms on the crowbar.
After a long time and a lot of errors, I get the result as flash content.
Please comment on what can be improved here and whether such a connection is acceptable. Thanks!
