ESP-WROVER-KIT is the other name for DevKitJ, it's designed to make use of this module.

Hi, Can you show us the schematic of esp32-wrover? We want to know how to connect PSRAM and Flash.

Thanks

Hi, All. Please help me recommend the candidate.

Just an update I have found a workaround to the random connection problem if I keep "Boot" button pressed esptool.py always works (even on Win7) Thanks for reporting this, hydrabus. I have reproduced this issue on Windows 7 with a v2 core board. On Windows there is a 4ms delay between when "EN" goe...

About your question: If you put the board in download mode first using buttons does it ever fail? It seems it always works when just plugged / powered on (so yes it seems to be software bug maybe in python script of in the code injected/executed by ESP32 ...). I just want to know if the issue I des...

It's same with ESP32-DevKitC of Espressif.

Thanks

Please Note: The error is same,

Why it writes 2635byte?

Try setting the baud rate to a lower value (either by changing the "--baud" argument on the command line, or the setting in "make menuconfig"). Thanks for your answer. But I use default baudrate 115200, It prompts the error. And I use 230400, It prompts the MD5 error like this http://esp32.com/view...
