Posted on August 01, 2013 at 17:29Dear gentlemen,
Yes, we support Boundary Scan STD_1149_1_2001 for all of our STM32 MCUs having JTAG . Indeed, The STM32F MCUs integrate two serially connected JTAG TAPs, the boundary scan TAP (IR is 5-bit wide) and the Cortex-M4 TAP (IR is 4-bit wide).
and our BSDL files are always 2 :
+ A BSDL File for the CortexMx TAP and is common to all STM32Fxx devices
+ Boundary scan BSDL Files for each STM32Fxx on different packages
In order to run boundary scan, always provide two BSDL files to your
JTAG Boundary scan tool: the ''CortexMx.bsd'' and your selected ''STM32xx_device_Package.bsd''.
The Cortex-M Tap should be bypassed and Keep NRST pin of the STM32 MCU low to be able to run test patterns.
For more details on the internal TAPs description refer to the Reference Manual (Not datasheet) of the selected STM32xxxx device , Section : JTAG TAP connection.
Production devices, BSDL files are available at web, but newer devices not yet ready, we will publish them as soon they are available. But you can contact me if you have a special demand while giving the exact part-number & package or to contact our FAEs, ST contacts.
Cheers,
STOne-32.
