DTR and RTS signal

[saeidfallah1132]

Hi community,
I am programming an STM32F103 microcontroller with CP2104 (USB-serial converter) in the USART1 bootloader via Arduino IDE.
It can program the chip successfully. I need DTR and RST signals to design an auto-program and reset the chip automatically.
I am checking the signal with an oscilloscope, but the two pins of CP2104 don't change during the programming stage.
I had some research and I figure out that it is required to add these two line in the board.txt file to enable the signal during the programming:
GenF1.serial.disableDTR=true
GenF1.serial.disableRTS=true

However, by adding these line, DTR and RST wouldn't change.
Could you please advise me on how can I enable these signals of the CP2102 during the programming?

Hi,
Reading this:
https://arduino.github.io/arduino-cli/0.21/platform-specification/#serial-monitor-control-signal-configuration

The disableDTR/RTS does not enable the signal during the programming but prevents Serial Monitor from asserting the control signals when that board is selected, that's all.

Programming via UART is manage by the STM32CubeProgrammer. Looking at the builtin bootloader specification, the UART does not use the DTR/RTS.

Do you mean there is no way to enable DTR/RTS signal on the serial port while I am programming my board with Arduino?
In the Arduino console it shows that flow-control is off:
**------------------------------------------------------------------
STM32CubeProgrammer v2.11.0
-------------------------------------------------------------------

Serial Port COM5 is successfully opened.
Port configuration: parity = even, baudrate = 115200, data-bit = 8,
stop-bit = 1.0, flow-control = off**

Could it be because of that?
Do you have any solution for that?

This is the stm32cubeprogrammer . Check in the user manual if it can drive them.

[fpistm]

Seems STM32CubeProgrammer able to set RTS and DTR signals level but honestly for default build-in bootloader in UART mode it is not used

And as stated "Flow control: must be always off."

Hello,

This is a late answer, but I just come to this problem and found the solution:
Arduino ide launch stm32CubeProg.sh script to program the stm32. It invoke the STM32CP_CLI.
this script is here for me : ... AppData\Local\arduino15\packages\STMicroelectronics\tools\STM32Tools\2.2.1. But it is easy to know where it is in your configuration, just go to arduino IDE -> file -> preferences and activate verbose case. Then launch an upload and look the console!

So you just need to modify the command ${STM32CP_CLI} -c port=${PORT} ${MODE} ${ERASE:+"-e all"} -q -d "${FILEPATH}" "${ADDRESS}" -s "${ADDRESS}" "${OPTS}" by adding rts=low (or high) dtr=low (or high) depending your case.
In my case:
${STM32CP_CLI} -c port=${PORT} rts=high dtr=high ${MODE} ${ERASE:+"-e all"} -q -d "${FILEPATH}" "${ADDRESS}" -s "${ADDRESS}" "${OPTS}"

And That's all Folks!
Hope this will help !
