ESP32-S3-N16R8 N8R2 Development Board Firmware Issues Backtrace

[droidblastnz]

Team,

I have stability issues with three nodes post flashing.

3x ESP32-S3 2.4GHz WiFi Bluetooth Module ESP32-S3-N16R8 N8R2 Development Board CORE Board Type-C ESP32 S3

the process...

Flash — 8MB:

Flash Node 0

python -m esptool --chip esp32s3 --port COM6 --baud 460800 write-flash --flash-mode dio --flash-size 8MB --flash-freq 80m 0x0 bootloader.bin 0x8000 partition-table.bin 0xf000 ota_data_initial.bin 0x20000 esp32-csi-node.bin

python provision.py --port COM6 --ssid "test_SSID" --password "********" --target-ip 192.168.2.130 --node-id 0 --tdm-slot 0 --tdm-total 3

Flash Node 1

python -m esptool --chip esp32s3 --port COM10 --baud 460800 write-flash --flash-mode dio --flash-size 8MB --flash-freq 80m 0x0 bootloader.bin 0x8000 partition-table.bin 0xf000 ota_data_initial.bin 0x20000 esp32-csi-node.bin

python provision.py --port COM10 --ssid "test_SSID" --password "********" --target-ip 192.168.2.130 --node-id 1 --tdm-slot 1 --tdm-total 3

Flash Node 2

python -m esptool --chip esp32s3 --port COM11 --baud 460800 write_flash --flash_mode dio --flash_size 8MB --flash_freq 80m 0x0 bootloader.bin 0x8000 partition-table.bin 0xf000 ota_data_initial.bin 0x20000 esp32-csi-node.bin

python provision.py --port COM11 --ssid "test_SSID" --password "********" --target-ip 192.168.2.130 --node-id 2 --tdm-slot 2 --tdm-total 3

Bring all three nodes online and watch the serial int of each with

python -m serial.tools.miniterm COM6 115200
python -m serial.tools.miniterm COM10 115200
python -m serial.tools.miniterm COM11 115200

All three have similar crashes

Backtrace: 0x4037890F:0x3FC9D6A0 0x4037746D:0x3FC9D6C0 0x4200D225:0x3FCCA290

read https://github.com/ruvnet/RuView/releases/tag/v0.5.0-esp32
read #301

Watchdog crash CPU 1: edge_dsp - flashed v0.4.3-esp32 and v0.5.0 same issue.

Tried full erase and re flash as above

python -m esptool --chip esp32s3 --port COM6 erase_flash
python -m esptool --chip esp32s3 --port COM10 erase_flash
python -m esptool --chip esp32s3 --port COM11 erase_flash

Note that when flashing
write_flash --flash_mode dio --flash_size

python is warning

write_flash is now write-flash
--flash_mode is now --flash-mode
--flash_size is now --flash-size
--flash_freq is now --flash-freq

write-flash --flash-mode dio --flash-size 8MB --flash-freq 80m

Ideas on where to next please?

Still have back traces but only seem to have a single node show up.

this shows my three nodes / IPs

Three ESP32 S3 Generic sensors been stable for hours. Found we had websocket issues and found this thread,

#272 pulled the latest build image but it appears the issue is still there?

issues with the ESP32 S3 once the websocket issue is resolved.
