so you are not sure if you are running the latest code? Did you resolve this? |
|
The problem surfaced with the latest code. The old code dated 2/20 worked but the last version I downloaded didn't. I see you just did an update for the chip id. I will download as of today and give it another run. UPDATE: |
|
i'll have in a few minutes a new update with new bootloader and all. Please give it a go once it's merged (5-10 minutes tops) |
|
Not a problem. Will try later today and let you know how it works. |
|
It's merged :) 376961d |
|
No luck. Still getting the same error. You want I zip the version that works? |
|
ok what board are you using exactly? |
|
Onehorse's ESP32 board. |
|
do you have that board selected in the menu? that one has specific issues with flashing ;) |
|
Yes I have that specific board selected in the menu. Had no problem when using the older version of the ESP32 Lib. Something seem to have changed between versions I am using. I first mentioned this in issue #334. Here is output from the IDE: |
|
The first production batch of ESP32 boards was shipped yesterday so I will be able to send me-no-dev one next week or so. Maybe this would be easier than remote debugging. I haven't updated the ESP32 Arduino core (afraid to!) since the first time I got the board to work using Igrr's bootload.bin file. I am sure once me-no-dev has the board the problem will get sorted out in short order. |

Thanks @kriswiner . Just wanted to let you know the issue with the new core. @me-no-dev and @kriswiner. As a hack I took the bootloader.bin file from the version that works and passed it in the one I just downloaded and it worked no problem. Didn't think about doing this until @kriswiner mentioned the bootload.bin file in your post. At least I have a workaround for the new core. Think @me-no-dev is going to like the board. I have to order another as backup now. Not sure what changed in the bootload.bin file. |
|
I'm waiting for the board :) will do my best once here! |
|
Thanks @me-no-dev. At least I found a work around to be able to use the new core, i.e., just use the old bootloader :) |
|
Yeah, that's what I have been doing, but I would rather be able to use the
stock Arduino core as it is. (and get updates through the Arduino IDE json!)

@mjs513 could you somehow publish the actual version of the bootloader you are using? I also have issues with the bootloader.bin from @kriswiner I got a different log though:
I am not sure what "Guru Meditation Error of type IntegerDivideByZero" means. Kind Regards, |
|
@RSchlenker Here's the bootloader that I am using. Good luck. Let us know if it works. Might help @me-no-dev. Mike |
|
Sill waiting the post to bring the board :) fingers crossed it will be soon |
|
@mjs513 Thank you for the bootloader. Robin |
|
I am having the same issue. |
|
@chevdor try the bootloader version in a previous post. Maybe it will help? |
|
@chevdor select 40Mhz in the board menu instead of 80Mhz and your blink code should work |
|
if the selected flash mode is QIO in the previous firmware then you will not be able to do the OTA on it so use the flash mode : DIO and i am working with 80Mhz and so there will be no effect of frequency on OTA |
Downloaded latest board files into IDE 1.8.2 and receiving the following error messages:
This first mentioned in #334 . Tried different upload speeds and did not work.
To test whether the problem is with the ESP32 or the IDE I copied the previous version of the library that I was using into the 1.8.2 hardware folder and uploaded the Blink sketch. It worked fine no problems. Yes it blinks. Not sure what version I have, but the json file is dated 2/4/17 along with most of the files. The make file is dated 2/20 if that helps.
Thank you
Mike
