Enrico Razzaboni posted a comment on ticket #153
Hi, after a lot of tests, now it works. i've added a sleep of 2 seconds after set reset pin to high
-
i don't see any difference, except the reply of stm32 micro
-
it's the .sh file with gpio and sleep command
-
here it is
-
stm32flash never failed from the command line. my host is not at limit (3/6% cpu)
-
Hi, i've tried also to run stm32 from bash file, and run bash file from qt. but i've the same result. bash code: #!/bin/bash PATH_GPIO_EXP="/sys/class/gpio/export" PATH_GPIO_DIR="/sys/class/gpio" RESET="5" C_BOOT="4" P_BOOT="3" sudo echo 0 > $PATH_GPIO_DIR/gpio$RESET/value sudo echo 1 > $PATH_GPIO_DIR/gpio$C_BOOT/value sudo echo 0 > $PATH_GPIO_DIR/gpio$P_BOOT/value /bin/sleep 4 sudo echo 1 > $PATH_GPIO_DIR/gpio$RESET/value sudo stm32flash -w $1 /dev/ttyUSB0
-
yes, i've the same issue
-
ok, here it is
-
ok, what you need?
-
stm32flash is running on embedded device with Yocto. you see windows screen because I've created a serial sniffer to watch what's going on. i attach a photo to undestand better
-
i've looked at the serial communication with serial sniffer. this is the result
-
no it's impossible :(
-
edit: there was an error on my code. QProcess *loadFirmware = new QProcess(); loadFirmware->start("stm32flash", QStringList() << "-b" << "9600" << "-w" << path << "/dev/ttyUSB0"); loadFirmware->waitForFinished(-1); qDebug() << loadFirmware->readAllStandardError(); qDebug() << loadFirmware->readAllStandardOutput(); output: "Failed to init device after retry.\n" "stm32flash 0.7\n\nhttp://stm32flash.sourceforge.net/\n\nUsing Parser : Raw BINARY\nSize : 301172\nInterface serial_posix: 9600 8E1\n\n" why...
-
ok i've tried this morning with this syntax and something change. but i've another error. code: QProcess *loadFirmware = new QProcess(); loadFirmware->start("stm32flash", QStringList() << "-b" << "9600" << "-w" << path << " /dev/ttyUSB0"); loadFirmware->waitForFinished(-1); qDebug() << loadFirmware->readAllStandardError(); qDebug() << loadFirmware->readAllStandardOutput(); output: "Error probing interface \"serial_posix\"\nCannot handle device \" /dev/ttyUSB0\"\nFailed to open port: /dev/ttyUSB0\n"...
-
but if you're sure that it not depends on your software, i'll find another solution
-
yes i've understood it. but id doesn't change.
-
yes, one example: gpio5.start("bash", QStringList() << "-c" << "echo 1 > /sys/class/gpio/gpio5/value");
-
are you sure that has nothing to do with stm32flash? because all other process works...

Error running stm32flash with QProcess (qt)

i've tried with a lower baudrate and it works... at this point i think is my harware issue. thank you for the help

Using boudrate 38400 i get this pi@raspberrypi:~ $ sudo stm32flash -w OxyMonitor_rev11.hex -b 38400 /dev/ttyUSB1 stm32flash 0.7 http://stm32flash.sourceforge.net/ Using Parser : Intel HEX Location : 0x8000000 Size : 47980 Interface serial_posix: 38400 8E1 written 1 bytes, starting with 0x7f read 1 bytes, starting with 0x79 written 2 bytes, starting with 0x01 read 1 bytes, starting with 0x79 read 3 bytes, starting with 0x31 read 2 bytes, starting with 0x00 read 1 bytes, starting with 0x79 written...

I'm using a custom board. i can load firmware over serial with Stm32CubeProgrammer. i've tested with more the one micro

for some reason if i try to use an high baudrate, my mcu doesn't enter in boot mode... look at this ( https://community.st.com/s/question/0D53W00001PvxvwSAB/stm32cubeprogrammer-connection-over-uart-error ) in fact if I set baudrate 38400 I get this error pi@raspberrypi:~ $ sudo stm32flash -w OxyMonitor_rev11.hex -b 38400 -c /dev/ttyUSB1 stm32flash 0.7 http://stm32flash.sourceforge.net/ Using Parser : Intel HEX Location : 0x8000000 Size : 47980 Interface serial_posix: 38400 8E1 GET returns unknown...
