Why this error flashing STM32F746BGTx ?

[Pavel A.]

I'm trying to flash a .bin file onto STM32F746BGTx  with CubeProgrammer 2.6.0.

Yes , not latest but STM32F746 is not quite a new thing so I'd expect it to work.

And get this:

16:11:01 : File : vvvvv.bin
16:11:01 : Size : 1026247 Bytes
 16:11:01 : Address : 0x08000000

 16:11:13 : Error: Data mismatch found at address 0x08027804 (byte = 0x5D instead of 0xE8)
 16:11:13 : Error: Download verification failed

Then flashed same file using the old ST-LINK utility, and it seems to work (*)

Debuggers do not complain (CubeIDE and IAR, with st-link)

But you know, half the things they did with the software and firmware relate to fixing actual bugs..

I'm really not sure there's a lot of value in relitigating failings that have already been fixed/addressed.

They fix a bug and drop in a couple more. Updating their tools always scares me.

 But they are good neighbors, not trying to kick Segger out of J-LINK business.
