Posted on December 12, 2017 at 00:37ST please help, this seems to be not trivial error with ST-Link Utility, I have also latest v4.1.0.0, trying to work with Nucleo L496ZG-P dev board:
sometimes same as above, sometimes after erase 1 then erase 2, 'full chip erase' does work.
But very much bigger problem: the utility bombs out programming a .bin file for the full 1-MB. So I broke it into half, and even bombs on trying to program a .bin file for lower half:
15:11:44 : The elf loader Program function fails.
15:11:49 : The elf loader Program function fails.
15:11:49 : Memory-Loader error
15:11:49 : Error occured during program operation!
15:11:59 : Programming error @: 0x0807FFFC
And fail for .bin file for upper half:
15:15:12 : The elf loader Program function fails.
15:15:17 : The elf loader Program function fails.
15:15:17 : Memory-Loader error
15:15:17 : Error occured during program operation!
15:15:27 : Programming error @: 0x0807FFF0
I think that a big clue for you is the difference of where it fails. In lower half, last line of 16 bytes has last 4 bytes as non-0xFFFFFFFF after a huge block of all erased values (just pad fill 0xFFFFFFFF). In upper half, last line of 16 bytes has all 16 bytes as non-0xFFFFFFFF after a huge block of all erased values (just pad fill 0xFFFFFFFF).
Makes me think that the ST-Link Utility is doing some form of 'fast flash program' like HAL API, programming blocks of 32 x 8-byte word size (or blocks of 256 bytes), but then gets tripped up by this last page with non-erased at end?
Anyway, this identical binary file (whether entire 1-MB, or half by half) will program just fine into a dev board with STM32F476RG.
So again, ST, please help with programming of Nucleo L496ZG-P dev board.
