esp32-s3 hello-world does not work #62

Closed DaniDD closed 2 years ago

DaniDD commented 2 years ago

Hello,

I try the hello-world example on ESP32-S3. If I start the example, I have this error, then Guru Mediatation and reboot. I dont know is this only an incompatible model, or is my firmware not correct? My output:

12:31:04.012 -> interpreter_make_new: model size = 2488, tensor area = 2064 12:31:04.012 -> Didn't find op for builtin opcode 'FULLY_CONNECTED' version '4'.

Thanks for this report. I'm seeing the same thing for regular esp32 builds.

I merged #28 as it seemed to be working but it looks like it was just compiling but not actually doing what it is supposed to which is to allow controlling which tflm ops are included in the firmware.

I'm tracking the fix for this on #63 for now I think you should try using this version which is before I merged #28: https://github.com/mocleiri/tensorflow-micropython-examples/actions/runs/1656246622 (at commit: c98c091ce686bf14af9f505ce3ff75ed4cc81a9b)

I reverted the merge of #28 and you should be able to download the updated board image form here: https://github.com/mocleiri/tensorflow-micropython-examples/actions/runs/1716379308

Thank you mocleiri für your fixes. The firmware for ESP32_S3 booting now and I can run hello_world. I have test ist with this build: https://github.com/mocleiri/tensorflow-micropython-examples/actions/runs/1716379305
