Hi all

I am using STMF429I Discovery Board. I am Using Keil V5. I have downloaded and Pack for STM32F429ZITx 2.7.0(2015-12-08_ DFP, Installed added ST- Link Utility and updated ST-Link firmware to V2J24S0.. I did all the setting in Options for Target  following STM company videos.. And once programmed successfully but from next time getting error as ''Internal Command Error'' then '' Error: Flash Download Failed -Target DLL has been cancelled''. Pl can anybody help me?

Thanking You.

Make sure it is using SWD and you have selected ''Connect under reset''. Make sure the ST-LINK Utilities are closed.

See if you can connect/erase with the ST-LINK Utilities, or if pulling BOOT[0] High improves things.
