[FEATURE] ESP32-S3-BOX(-3) support

[luciust]

There's a product called ESP32-S3-BOX and ESP32-S3-BOX-3 which is a ready developer kit - comes with touch display and exposed PINs. Would make a good base for the project. Don't want to link to the commerial pages, you can easily look it up.

[andreock]

Do you own one so you can test the firmware?

[luciust]

Sure, I can even brick it, so let's have a go. The one I got is now considered obsolete (as the -3 replaced it) but it sports: ESP32-S3-WROOM-1-N16R8, 16 MB QSPI flash, 8 MB Octal PSRAM and a touch 2.4-inch display. Let me check if I can flash it - if so we can later take a look at supporting that screen... Example product page and datasheet: https://www.mouser.be/ProductDetail/Espressif-Systems/ESP32-S3-BOX

capibaraZero_0_5_0_esp32s3box.zip Can you try to flash this firmware?

python3 esptool.py --chip esp32s3 --port UPLOAD_PORT --baud 460800 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size auto 0x0000 bootloader.bin 0x8000 partitions.bin 0xe000 boot_app0.bin 0x10000 firmware.bin

Different results:

Now the screen flahes white - black every second and I got on the console 'Amiga Stuff - Guru Meditation:

Rebooting...

[andreock]

there was a problem with a GUI, I removed a function that is necessary for the GUI initialization. Can you try this one? Thank you capibaraZero_0_5_0_esp32s3box_test3.zip

[luciust]

Hey, no problem, no need to aplogize, just push the test firmware, as mamy as needed. Flashing tomorrow!

[luciust]

This time i got 45 degrees menu on the device, screen is working:

[andreock]

nice, next time I will add navigation button support, SD card and try to fix screen rotation.

In future I will add also touch support maybe, yesterday I bought a touch display so it will be supported for sure

[andreock]

capibaraZero_0_5_0_esp32s3box_test4.zip Here you go, follow this pinout for the SD card:

• CS 10
• MOSI 11
• SCK 12
• MISO 13 I didn't put the navigation button for the moment.

[luciust]

Thanks, will test - planning to solder SD card adapter next week...

[luciust]

That gave me white screen no console... SD card not connected yet.

[andreock]

I'm starting to think there's some problem with the serial. Try this one please. capibaraZero_0_5_0_esp32s3box_test5.zip

[luciust]

Hope I'm not frustrating you - but test5 gave me black screen, no console activiity, just some reset info when tried to flash it again. Went back to test3 firmware just to check and it worked as previously with tilted 45 screen.

[andreock]

capibaraZero_0_5_0_esp32s3box_test6.zip Try this one please

[luciust]

Thanks, raporting back in the evening, should have the SD card, as the pins are easily exposed and I got adapter that needs no soldering. I start to like that dev-kit, not to mention your quick support on this.

[luciust]

Screen and orientation is OK with test6! SD card later...

[luciust]

Connected the SD, nothing is blown, no activity on console tough!

[andreock]

If you have SD card, can you test the capibaraZero_0_5_0_esp32s3box_test5.zip please? Test6 doesn't have SD initialization

[luciust]

OK, going back to test5 gives me, regardless if SD card is powered or not powered via 3.3V

[andreock]

Can you flash also test4, to see if serial give some debug information at least. thanks

[luciust]

Hello,

tested both 4 and 5, no luck:

I had one partitnion on 4GB SD card - it hasn't been touched, also deleted it and no other changes happen after testing 4 or 5. Console is mute, but if I force file download - I get an ESP32 banner. So it is working presumably, just not telling me much.
