=======================
How to use BSDL Files :
=======================

The STM32MP2 MCUs integrate two serially connected JTAG TAPs, the boundary scan
TAP (IR is 5-bit wide) and the Cortex-A35 and Cortex-M33 TAP (IR is 4-bit wide).

The package contains :

   + A BSDL File for the Cortex-A35 and Cortex-M33 TAP and is common to all STM32MP2 devices.

   + Boundary scan BSDL Files for each STM32MP251_253_255_257 device on different packages :

	  o TFBGA436
	  o VFBGA424
	  o VFBGA361
          o TFBGA361
	  
+ Boundary scan BSDL Files for each STM32MP231_233_235 device on different packages :

	  o VFBGA424
	  o VFBGA361
          o TFBGA361

+ Boundary scan BSDL Files for each STM32MP211_213_215 device on different packages :

	  o VFBGA361
	  o VFBGA289
          o VFBGA273
          o VFBGA255
	   

In order to run boundary scan, always provide two BSDL files to your JTAG Boundary scan tool:
the "CortexMx.bsd" and your selected "STM32MP2xx_device_Package.bsd".  

WARNING : Do not combine both BSDL files in a single TAP with 9-bit wide !

For more details on the internal TAPs description refer to the Reference Manual
of the selected STM32xxxx device , Section : JTAG TAP connection.
========================
* V3.0 - 06-October-2025  
========================

  + Added BSDL files for STM32MP211_213_215 devices.
========================
* V2.0 - 10-February-2025  
========================

  + Added BSDL files for STM32MP231_233_235 devices.
  + Added the TFBGA361 package for the STM32MP251_253_255_257.
========================
* V1.0 - 21-June-2024   
========================

  + Created with BSDL files for STM32MP251_253_255_257 devices.
Comment: For the VFBGA424 package, the pin identifiers for VDD, VDDA18PPL3, VDDCORE, VDDCPU, VDDGPU, VDDQDDR, and VSS 
that originally start with the number 1 have been changed to start with the letter I to ensure compatibility 
with the BSDLCheker tool, as retaining the number 1 leads to an error.
