hi,

 

i am using STM32F401RBT6 (LQFP64) and i can't connect ST-LINK/V2 ISOL (FW V2J27S6) to program my board.

i always have "no target connected". i tested with SMT32_utility and MDK-ARM.

pin60 boot0 = 0, pin7 NRST = 1, pin46 TMS to ST-LINK/V2 pin7, pin49 TCK to ST-LINK/V2 pin9, pin55 SWO to ST-LINK/V2 pin13, gnd to ST-LINK/V2 pin4 and i tried also 3.3V to ST-LINK/V2 pin1. 

i checked power supply 3.3V on my device (pin 13,19,32,48,64) gnd (pin 12,18,31,47,63). i have capacitor to gnd on pin30. voltage is 1.2V.

Where is my problem? is missing something?http://www.st.com/content/ccc/resource/technical/document/user_manual/65/e0/44/72/9e/34/41/8d/DM00026748.pdf/files/DM00026748.pdf/jcr:content/translations/en.DM00026748.pdf

i have nucleo_F401RE board and i tried to connect ST-LINK/V2 ISOL to CN4 with CN2 jumper removed = same problem.

ST-LINK/V2 ISOL works good because i program custum board with STM32F439.  

Please i need support!

 

 

thanks
