Document how to flash from the CLI #28

Open kubark42 opened 1 year ago

kubark42 commented 1 year ago

A couple users have asked for beginners guides, so I thought it would be helpful to document in the README.md how to flash when using macOS or Linux.

Flashing from non-Windows systems is possible with the correctly formatted command. With esptool, the following worked for me on macOS, when flashing a T5-4.7 (which IIRC is a basic ESP32, not an S2 or S3):

"~/Library/Arduino15/packages/esp32/tools/esptool_py/4.5.1/esptool" --chip esp32 --port /dev/tty.usbserial-54350321661 erase_flash
"~/Library/Arduino15/packages/esp32/tools/esptool_py/4.5.1/esptool" --chip esp32 --port /dev/tty.usbserial-54350321661 --baud 460800 write_flash -z 0x1000 ~/Downloads/LilyGo-MicroPython_esp32_LILYGO_T5-4.7_MPY-d7919ea71_IDF-8153bfe412_B20230222_a8ff3ecace.bin

Please note that to use this above command correctly on other computers, it is necessary to specify the locally correct serial port and binary blob names.

P.S. I had to try a couple different baud rates for it to work 100% of the time. 460800 seems to be the fastest I can go and never experience uploading failures.

Ok, mine sees to work now, but only if I flash it to 0 not to 0x1000, odd?

Hah, that might solve my mystery! A while ago, I had flashed an ESP32-S3 and I had saved the command I had used. The address was 0x0000, and not 0x1000. However, yesterday, when I was trying to flash my T5 –4.7 with that exact same command, it would give me a similar error to the one you mentioned in https://github.com/Xinyuan-LilyGO/lilygo-micropython/issues/24#issuecomment-1483913505. Using 0x1000 resolved that problem. Maybe an ESP32-S3 needs 0x0000 and a regular ESP32 needs 0x1000?

This is to keep consistent with the original micropython burning method.

@ChrisKahrs Thanks for noting that the ESP32S3 firmware.bin MUST be flashed to 0x0000 NOT 0x1000 (like the ESP32 build). I was completely stuck as to why none of the .bins for my new T5-PLUS units would run...

Where can I find firmware for T3S3 v1.2 board? I don't see it listed in Supported Boards section of Readme. So I tried using the one available on micropython's website, but it fails too.

Has anyone successfully installed micropython on T3S3 v1.2?

Below command says that the firmware is not built for ESP32-S3, Can anyone help me with how to build it for S3?
