Not able to dump/load program via ST Link Programmer for STM32H743 MCU.

[LokeshIchchangi]

Hi everyone,

We are facing issue is  " Not able to load/dump code via ST -LINK Programmer " and it's showing as error mentioned below. please help us to resolve this kind of issues or please suggest any idea to implement it as soon possible.

Check banking in Option Bytes, show options.

Check board implementation, especially VCAP capacitor values placed, and observed voltage on pins.

@Tesla DeLorean 

especially VCAP capacitor values placed, and observed voltage on pins --> where these will get pls let us know??

[LokeshIchchangi]

 Option Bytes,

Hello,

Is it a custom board? if yes check your HW especially VCAP and decoupling capacitors. You need to refer to the AN4938 Getting started with STM32H74xI/G and STM32H75xI/G MCU hardware development. Figure 18 as a schematics reference.

If you have an ST board, do you face the same behavior?

In the datasheet:

Also Use STM32CubeProgrammer tool instead of STLINK-Utility as it is obsolete.

[LokeshIchchangi]

@Tesla DeLorean 

VCAP capacitor is placed and observed voltage is at VCAP 1 and 2 is  1.0 volt.

[LokeshIchchangi]

@SofLit 

Yes We are using custom board.

I have ST Evolution Board we tested no issue is observed it.  

[SofLit]

Check you schematics versus the schematics reference in AN4938 Getting started with STM32H74xI/G and STM32H75xI/G MCU hardware development

[Tesla DeLorean]

Should be closer to 1.25V

Capacitors, multiple 2.2uF each, or single common 4.7uF. The values here are important, you need adequate bulk capacitance.

Presuming this is your design, and built by your PCBA

Show Option Bytes from STM32 Cube Programmer, the old ST-LINK Utiities haven't been updated in a few years. Try doing a write/verify of a 2MB binary file to confirm functionality there.
