does ladybug have read protection?

[laterrps]

i have been trying to flash it and i cant

[kriswiner]

Little more information required.

Are you using the Arduino IDE?

Did you put it into boot mode first (press and hold boot, press and release restart buttons)?

I am using keil uvision and stlink v2

[GrumpyOldPizza]

Read protection is not enabled. I flash STM32L4 all the time using ST-Link V2. Never used Keil uVision, so perhaps it's just a setup question on your end.

N.b. the debugger cannot break in (and flashing) when the chip is in a low power mode. So pressing toggeling RESET while BOOT is pressed is a good way to get the chip into a good state.

can you help me?

[laterrps]

:/

[GrumpyOldPizza]

I have zero idea. Does the Arduino IDE work (which is what this github here is about) ?

[laterrps]

can you help me please?

[laterrps]

yes it is working! on arduino ide

[GrumpyOldPizza]

Ok, so it's either an issue with the ST_Link adapter or the program you are using. Have you tried to update the firmware on the ST-Link (let's assume you have a cheap clone from ebay ...) ? Have you tried to flash this with the official ST ST-Link software to eliminate a Keil uVision problem ?

If it would be read out protected, the normally dfu-utils would throw an error, and the Arduino IDE would fail to flash a sketch.

[laterrps]

OK ok!!! I dont understand the reason because i can not to flash it!

[laterrps]

I have programmed now! but it is necessary to conect the rst pin in rst button, plus swdio swclk gnd and 3v3

[laterrps]

or how do you program it with st link?

[laterrps]

can you help me with a schematic?

[kriswiner]

There is a schematic on the Tindie page.

i meant the schematic showing me how you programm it

[GrumpyOldPizza]

There should be a configuration option to use the internal reset via SWD.

Didn't you just say you did program it?

Can you program the Nucleo board or the discovery board?

Maybe the ST forum would be a better place. This site is for the Arduino core.

I am using SWDIO, SWCLK, GND and VCC.

maybe is the programmer that i am using!! thank you very much!!! seriously!! you help me a lot!

[GrumpyOldPizza]

Well, we decided against exposing a RESET pin. Mainly because you can press RESET manually, and for debugging a live system, the internal reset that the debugger can trigger via SWD is good enough anyway.

@GrumpyOldPizza i have selecter some diferent options in keil uvision but only this work and i have to "make contact" with a jumper on the button reset pin

[laterrps]

@kriswiner thank you i talked to you because i consider you experts! and thank you very much for attend my questions! seriously i am sorry if i am disturbing your work!! best regards!

[laterrps]

@kriswiner yes i have not problem with nucleo board now i am working with ladybug ! but i programmed it now, thank you very much

@GrumpyOldPizza which version of file do you send by ST-Link 32 V2 .hex file or .elf?
