Installation Problem #83

Closed tom-niddatal closed 6 years ago

tom-niddatal commented 6 years ago

I am trying to install LUA RTOS on my ESP32S dev board. Whatever I tried, I got stuck on the installation process. Tried it first with the wcc from a MAC. With this MAC I am able to communicate with the board with the Arduino IDE. on cu.SLAB_USBto UART.

I can see in the serial monitor that the board is enteeing the download mode, but wcc has no progress. I tried the same on Windows, same problem

Any ideas?

regards Tom

Mmmmmm ....

I haven't this board for test. Please before running wcc do the following from the esp-idf older:

python components/esptool_py/esptool/esptool.py --chip esp32 --port /dev/.... T --baud 921600 erase_flash

After flash is erased run wcc again.

Because we don't have feed back we close this issue. Please, reopen the issue in case of problems.

I can confirm/reopen this issue with a more concrete example while running on OSX and using the precompiled OSX wcc as stated in the documentation:

(esp32) brainstorm:~ romanvg$ esptool.py  --chip esp32 --port /dev/cu.usbserial-FTYKHBJT --baud 921600 erase_flash
esptool.py v2.1
Connecting....
Chip is ESP32D0WDQ6 (revision 0)
Uploading stub...
Running stub...
Stub running...
Changing baud rate to 921600
Changed.
Erasing flash (this may take a while)...
Chip erase completed successfully in 4.4s
Hard resetting...
(esp32) brainstorm:~ romanvg$ wcc -p /dev/cu.usbserial-FTYKHBJT -f -ffs
Can't connect to any board at port /dev/cu.usbserial-FTYKHBJT.

Available serial ports on your computer:

/dev/cu.lpss-serial2
/dev/cu.Bluetooth-Incoming-Port
/dev/cu.usbserial-FTYKHBJT

(esp32) brainstorm:~ romanvg$ wcc -ports
Available serial ports on your computer:

/dev/cu.lpss-serial2
/dev/cu.Bluetooth-Incoming-Port
/dev/cu.usbserial-FTYKHBJT

All other toolchains (arduino, micropython, plain screen/picocom) behave correctly, only wcc does not seem to be able to send commands to the /dev/cu.usbserial-FTYKHBJT for some reason :/

My board is a generic ESP32 and it is in download mode when trying to do all this on OSX 10.12.6 Sierra with an original FTDI cable:

ets Jun  8 2016 00:22:57

rst:0x1 (POWERON_RESET),boot:0x1 (DOWNLOAD_BOOT(UART0/UART1/SDIO_FEI_REO_V2))
waiting for download

Reconnecting/rebooting/resetting does not help with wcc, all other programs/programmers/frameworks work :/

Hi @brainstorm,

Can you give us much information about the FTDI cable / board that your are using, such as the URL links?

Thanks!

brainstorm commented 6 years ago

The cable is a "ftdi ttl232rg" and it is working properly with Lolins, Wemos and all other boards I throw at it, so no drivers issue or similar.

The board is a custom esp32 one, but the board is not the problem either since I can flash esp-idf code, mongoose-os and even micropython.

Maybe we can check this issue together, if you are near us ... We can plan a meeting in Citilab - Cornellà.
