GPIO not working on STM32L462VE Topic is solved

[zie]

Hello
I have adapted ChibiOS on my own board with STM32L462VE.
(STM32_Registry to some other Files).
As Linkerfile I copied STM32L432xB.ld to
STM32L462VE.ld and change

flash0: org = 0x08000000, len = 512k
and
ram0: org = 0x20000000, len = 160k

STM32L462VE is used in the Makefile,

I can compile and the SW works with ST-Link and JLink on my board.
But no IO pins on Hardware are changed.
The SW writes to the registers, which change in Periheral View and Memory, but not on the hardware.

Any Ideas what could be wrong?

The GPIO on this board works with Atollic true Studio an CubeMx.

Have you adjusted board files for your board? It is also possible that the L462 has other differences to be addressed.

You could also inspect the GPIO registers and verify for correct values after PAL operations.

Hi

Yes, i have adaptet also the boardfile:

subtype = STM32L462xx
and set all the GPIO (in/out etc.)
the Hal_version is 5.0.x in the bordfile

what other differences can i config in the board-file?


The GPIO Registers are changing, but not the real outputs. The GPIO Registers are at correct address. GBIOB ODR = 0x48000414
And the config in the Registers also loos fine for me (MODERx = 1)

I tryed debugers openocd and st-link V2 and JLink.
I also tryed to flash the uP with stlink utility, alswase the same, no output on Hardware.

Any Idea?
Thanks and Regards
Felix

If ODR is correct then you should check your settings in board.h, are the pins programmed as output?

hi
i think, they are outputs : GPIOB Pins 12..15

from board.h

it look like i worked in a simulation, but i am connectet with st-link on my board.....

If the GPIO is being written I can see the following possible causes:

1) The GPIO is not programmed as you expect it to be, you should inspect the other registers.
2) Measurement error.
3) Something on the board is driving pins high or low.

Hi Giovanni

Thanks for your help!
I have a measurement problem... Ground from Linux PC via USB ...

That's why it was working with Atollic Studio on Win7 Pc.
Many thanks for your help. I am excited about your OS.

Felix
