Hi @jayaprasad,

Unfortunately, TensorFlow does not support building on Windows. You can try to use a different OS or docker.

Hey @kiruthika it will be easy to follow arduino starter guide and flash bootloader carefully.

@lakshana Sounds cool!

@andycadams2011 As far as I know, yes.

Hi @ml

From your description it looks like the LDO (5V-> 4V) of IC5 is broken. According to the specification, the maximum voltage for this LDO is 6V.

It's possible that the USB power supply has exceeded 6V and the LDO has been damaged. Maybe you used an adapter or battery that doesn't properly comply with the USB-PD standard.

In the Spresense documentation you can find:
"Powering the Spresense board using a conversion adapter for USB Type-C AC adapter etc. to microB may result in a voltage exceeding the VBUS withstand voltage, which may destroy the Spresense board. (Conversion adapters with Type-C receptacle connectors are non-USB standard compliant)."

Additionally, please see block diagram:

Hi @KamilTomaszewski

Thank you for your reply. I will do as you said.

@kamiltomaszewski thank you very much, it's exactly what I was looking for 🙂

@kamiltomaszewski it appears that after a client connects to the device that the linkstatus stops reporting that the ethernet cable is disconnected

Hey @KamilTomaszewski ,

ok, good to know. Thank you for your support!

Dear @kamiltomaszewski,

Thank you for your prompt reply.
I will try to update the esp8266 firmware and contact you later.

Best regards,

Hi @pnj Everything is installed correctly. There is no need to have the ${workspaceFolder}/.vscode/include folder. IIf you don't want to be warned about missing folder then you can remove this line (line 10) from the c_cpp_properties.json file.

Hi @kamiltomaszewski,

sorry for the late reply.
Yes, I've tried it and still there is an offset in Voltage which seems to be not LOW for the load cell.

Still the load cell is not working on the Spresense.

I am a developer in a slightly different field, but your post helped me with some things, thank you 👍

@jithul said in Flash gets stuck at 'Saving package to "nuttx"' in Spresense:

@KamilTomaszewski

Thanks for your quick response, I tried but ended up with below message

I am not able to install these, is this intended? Can you advise please?

Jithul

The issue resolved after factory reset (recovery) and re-flashed the bootloader, thanks for @KamilTomaszewski for the great support

Hi @jithul

First of all, I would like to confirm whether a hard fault occurs during the execution of function dnnrt.forward();?

Secondly, if you want to analyze the hard fault log you got, you can try the instructions from: https://forum.developer.sony.com/topic/66/up_assert-assertion-failed-at-file-manager-audio_manager-cpp-line-649-task-init/8

Please try this and let me know what you got.

Best Regards,
Kamil Tomaszewski

@nicibume Could you please share this model (sony_nabla.nnb) with me?

My e-mail address: kamil.tomaszewski@sony.com

Hi @mezmerizer

On Spresense you can use sampling frequency up to 512kHz.

To achieve this please see the recommended configuration in https://developer.sony.com/develop/spresense/docs/sdk_tutorials_en.html#_adc_sampling_frequency

b9da53c5-6f5c-41f7-b91d-8088bd5a4dcc-image.png

It is also possible to use the new configuration in the Arduino IDE. To do this you will need to create a new exported SDK. In this repository you will find instructions on how to prepare a custom Arduino package for Spresense: https://github.com/sonydevworld/spresense-arduino-compatible

Thanks to this you will be able to use your own Spresense SDK with your own ADC configuration.

The current implementation of the Camera library does not support Camera.takePicture () function within the interrupt service routine (ISR). Kernel panic is expected. Unfortunately, but the same will be with the Spresense SDK.
