stlink info unknown device

[CChav.1]

I'm using the board SPIN3202. When but I can't flash. When acces to stlink info it displays

Found 1 stlink programmers

 version:  V2J39S27

 serial:   0670FF545551677867033851

 flash:   0 (pagesize: 0)

 sram:    0

 chipid:   0x0000

 descr:   unknown device

And when I wan't to connect to the board

st-flash read dummy.bin 0 0xFFFF

st-flash 1.7.0

2022-11-30T13:48:06 ERROR common.c: Can not connect to target. Please use 'connect under reset' and try again

Failed to connect to target

So I tried to connect to it using connect under reset it displays

st-flash --connect-under-reset

invalid command line

command line:  ./st-flash [--debug] [--freq=<KHz>] [--serial <serial>] reset

  <addr>, <serial> and <size>: Use hex format.

  <fsize>: Use decimal, octal or hex (prefix 0xXXX) format, optionally followed by k=KB, or m=MB (eg. --flash=128k)

  <format>: Can be 'binary' (default) or 'ihex', although <addr> must be specified for binary format only.

  <area>: Can be 'main' (default), 'system', 'otp', 'optcr', 'optcr1', 'option' or 'option_boot_add'

print tool version info:  ./st-flash [--version]

example write option byte: ./st-flash --area=option write 0xXXXXXXXX

On selected targets:

example read boot_add option byte: ./st-flash --area=option_boot_add read

example write boot_add option byte: ./st-flash --area=option_boot_add write 0xXXXXXXXX

example read option control register byte: ./st-flash --area=optcr read

example write option control register1 byte: ./st-flash --area=optcr write 0xXXXXXXXX

example read option control register1 byte: ./st-flash --area=optcr1 read

I used STM32Cube Programmer however can't connect to it and it says.

Can anyone help me, please?

Check the schematic.

Make sure the JP8 reset jumper is present, so that "connect under reset" mode might function.

And perhaps use JP9 to put the STM32 into the System Loader.

Use STM32 Cube Programmer, little support here for third-party tools.

Thanks! I did but still can’t connect it. I’ve used STM32 Cube Programmer but can’t connect to the board either it shows

11:01:23 : STM32CubeProgrammer API v2.11.0 | Linux-64Bits

Also I’ve noticed that as soon as I connect it LD1 blinks and then turn red and when I checked

STM32_Programmer_CLI -l usb appears

I had this problem after a couple of re-flashing my test-programm:
st-flash refused to connect
however
"st-info --probe" still worked
After a "st-flash --connect-under-reset  erase" while keeping the boot0 = 0, st-flash worked again.
I presume, the bootloader vector got corrupted, and a full erase did the job.
