I have a board, where a program is keeping the Serial Link 100% busy and now it does not respond to new program uploads. Even with Flash Download Tool I get error...
test offset : 0 0x0 case ok
Uploading stub... Running stub... Stub running... Exception in thread Thread-1: Traceback (most recent call last): File "threading.py", line 932, in _bootstrap_inner File "download_process.py", line 678, in run File "espDownloader.py", line 601, in flash_download_test File "espDownloader.py", line 781, in flash_download_func File "espDownloader.py", line 697, in esp_stub_and_set_baud File "esptool\loader.py", line 916, in run_stub File "esptool\targets\esp32s3.py", line 232, in init File "esptool\targets\esp32s3.py", line 165, in uses_usb_otg File "esptool\loader.py", line 689, in read_reg File "esptool\loader.py", line 375, in command File "esptool\loader.py", line 307, in read File "esptool\loader.py", line 1415, in slip_reader esptool.util.FatalError: Serial data stream stopped: Possible serial noise or corruption.
Any Idea how I can stop the serial noise and that the bootloader accepts commands??? Thx for any hint.
