Connection to F100 Discovery board lost with a Cube project

[LMI2]

Posted on July 27, 2015 at 01:12

I have a Discovery board with

STM32F100RB MCU

. It looks like this

http://www.st.com/web/en/catalog/tools/FM116/SC959/SS1532/PF250863?sc=stm32vldiscovery

When I program it with software from it's page

http://www.st.com/web/en/catalog/tools/PF257914

The JTAG/SWD connection is normal but when I program a hex file from Cube the connection is immediately lost. 02:07:19 : [GPIOToggle.hex] opened successfully. 02:07:21 : Memory programmed in 0s and 359ms.

gpiouart1

is a Cube project. 02:07:46 : [gpiouart1 Con1_27_07.hex] opened successfully. 02:07:49 : Memory programmed in 0s and 578ms. 02:07:51 : Disconnected from device. 02:07:51 : Connection to device is lost: check power supply and debug connection. 02:07:51 : If the target is in low power mode, please enable ''Debug in Low Power mode'' option from Target->settings menu. I can't find any big differences in IDE settings. Only include files are different. So not a Keil problem, I think. Yes, It is getting late, but what could be the problem.

Does the ST-LINK have current firmware?

What EXACTLY is the software doing? Classic reasons the debug connection fail are that a) You reprogram the JTAG/SWD pins to other functions, b) You put the part into a low power or standby state. Can you regain control with ''Connect Under Reset'', or BOOT0 = HIGH, type approaches?

Hi mich.lei,

Did you reset the board? Could you precise which example of the firmware package you are running? -Shahrzed-

Clive and Shahrzed

My code does very little, it toggles PC8 and PC9 pins, the leds.of the demo board and sends a test strings along usart (PA10) and PA9. I'll put the code without comments at the end of this message. How is BOOT0 = HIGH command used? I think the ST-link has current firmware, it has ''V1.JS0 STM32 Debugger'' firmware. I have only tried ''stsw-stm32078\an3268\stm32vldiscovery_package\Project\Examples\GPIOToggle\MDK-ARM'' example. I am able to use the card by keeping reset switch down while I click the connect icon, so the board is not lost. This is main.c from the Cube with my code.

Connect the BOOT[0] pin to VDD?

Won't this NUKE the debug pins too? WHY are you doing this?

GPIO_InitStruct.Pin = GPIO_PIN_0|GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3
|GPIO_PIN_4|GPIO_PIN_5|GPIO_PIN_6|GPIO_PIN_7
|GPIO_PIN_8|GPIO_PIN_11|GPIO_PIN_12|GPIO_PIN_13
|GPIO_PIN_14|GPIO_PIN_15;
GPIO_InitStruct.Mode = GPIO_MODE_ANALOG;
HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

PA13 = SWDIO

PA14 = SWCLK This is the debug interface, if you reconfigure/break these pins the debugger won't work, don't do it...

That analog pin feature is from the Cube:''Set all free pins as analog (to optimize the power consumption)''. I disabled that setting, but it didn't help.

Good to to know about the Boot0.

Any news.

I have tried what has been suggested. For instance PA13 and PA14 and all the rest are at reset state and so on. It would be nice to know if this is a bug or not.
