Beginners Question: Not flashable - problem with the bin files? #31

Hi i tried to flash two ESP32 with the ESPDownloadTool v3.8.5 with your settings. UnicodeDecodeError: 'gb2312' codec can't decode bytes in position 18-19: illegal multibyte sequence is the response.

I used Putty for the serial output: rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) flash read err, 1000 ets_main.c 371

Maybe this has something to do with your last commit? I also tried an older version of the DownloadTool.

Alternatifely, I dont get the esptool to install on linux nor on windows.

Any ideas?

Did you download the binaries separately with the browser. Perhaps you corrupted them during download. Please try to download the zip-file and extract the binaries from there. This is the safer way...

Hey. I have that same problem. Did you find any solution?

martin-ger commented 3 years ago

The binaries are okay - please try the zip download and in case of trouble a lower baudrate for flashing.

I did what you said but still: When I try to flash it in flash download tool v2.3 it gives no surch file or directory error. (for boot files) When I try to flash it in flash download tool v3.8.5, UnicodeDecodeError: 'gb2312' codec can't decode bytes in position 15-16: illegal multibyte sequence error.

The ESP Download Tool needs to be checked on the option "DoNotChgBin". I had the same option you described and was able to continue after checking that option.

Probably a download error - try to download the complete repo as zip and extract the binaries from there.

Speculation. I for my part did not download the archives again but succeeded using the mentioned flag. I noticed this has been active for the ESP8266 variant.

I hope we can get others to validate one of the approaches to have a solution at hand.
