Heltec ESP Lora32 V3 keeps crashing #105

Open plonxyz opened 1 year ago

plonxyz commented 1 year ago

Hi I tried to use an Lora Example provided by heltech on arduino IDE.

Somehow my Boards keep crashing with a checksum error:

ESP-ROM:esp32s3-20210327 Build:Mar 27 2021 rst:0x5 (DSLEEP),boot:0x8 (SPI_FAST_FLASH_BOOT) pro cpu reset by JTAG SPIWP:0xee mode:DIO, clock div:1 load:0x3fce3808,len:0x43c load:0x403c9700,len:0xbec load:0x403cc700,len:0x2a3c SHA-256 comparison failed: Calculated: dcde8d8a4817d9bf5d5d69a7247667264e4e10ac7493514868b61f5aa6146539 Expected: ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff Attempting to boot anyway... entry 0x403c98d8

Does anybody know how I can fix this issue?!

Thanks!

see my comment on #106 for how to fix this on the V3 board. You need to download a new version of esptool (program that flashes the ESP32). The one provided by this library is too old and doesn't support the newer ESP32-S3 that comes on the V3 boards.

maybe also try other examples (for example i tried display api and the first exampel i looked at crashed but the one that interfaced directly with SSD1306Wire worked )

I have a similar check sum issue, for which bitrot-alphas solution from #106 (see above) seems to not resolve. The chip does load and function (Runs the factory test with WiFi, LoRa etc) As seen below there is a failed checksum. @plonxyz have you had any luck resolving this? @bitrot-alpha you seem to have a especially good skills in this department, any further advice?

I haven't been able to determine the exact cause of the checksum error, other than that Heltech seems to be using esptool somewhat improperly.

For anyone else wondering about this, take a look at Espressif's "Flashing Firmware" page. There's a good note there about how to make the Arduino IDE show the command it's using for esptool https://docs.espressif.com/projects/esptool/en/latest/esp32/esptool/flashing-firmware.html

sorry @Shaedo , I never tried it ..
