Problem with flashing firmware.bin using Espressif tool #32

Open pganson opened 8 months ago

pganson commented 8 months ago

I downloaded the Espressif flash download tool, v3.9.4 and the T-Embed project from this github repository. I am able to use the "erase" button and also to flash the firmware.bin file to my T-Embed.

But, then when I reboot the T-Embed, I get "Invalid header: 0xFFFFFFFF" continuously on the serial output from the T-Embed. The T-Embed appears to be in a reboot loop; the USB device on my computer keeps disconnecting and re-connecting.

Yes, my settings are the same as instructed.

You did not check the firmware you need to burn. image

I'm getting a timeout during the download of the firmware.bin image to the T-Embed. I've tried changing the baud rate (all the way to 115200) but it has no effect. I also tried two different ports on my laptop - USB-A and USB-C.

Do you have any ideas for something else to try ?

Hi @pganson, I encountered the same issue. Espressif released an updated version of their firmware flash tool which resolved the problem for me. You can download it here: Espressif Flash Download Tool 3.9.6. Hope this helps
