boards/stm32f769i-disco: enable FMC with SDRAM support by gschorcht · Pull Request #19851 · RIOT-OS/RIOT

gschorcht · 2023-07-28T12:48:05Z

Contribution description

This PR enables the FMC support on the stm32f769i-disco board and the on-board SDRAM MT48LC4M32B2B5-6A with 16 MByte.

The PR also includes a very small documentation fix for the stm32f746g-disco board (commit
f761e2d) and removes double empy line in the test app tests/periph/fmc.

Testing procedure

tests/periph/fmc should succeed, just compile and flash the app with
```
BOARD=stm32f769i-disco make -C tests/periph/fmc flash term
```
tests/sys/malloc should also use the SDRAM. Use
```
USEMODULE=periph_fmc_sdram CFLAGS='-DCHUNK_SIZE=131072' \
BOARD=stm32f769i-disco make -C tests/sys/malloc flash term
```
and check that the heap also uses the memory in the range from 0xc0000000 to 0xc0fffffff.

UPDATE: Tested with a stm32f769i-disco board.

@dylad According to the authorship of the board definition, I suspect you have a stm32f769i-disco board, which I do not. May I kindly ask you to test the PR on this board? Testing the FMC on this board would be very interesting since it is the only supported board so far that uses the the FMC peripheral and a SDRAM with 32-bit data bus width. The FMC was already tested extensively in PR #19843 for SDRAMs with 16-bit data bus width.

The PR itself is not that spectacular, we have already used the configuration provided in this PR several times in PR #19843 and it is simply copied from such a board. The only difference are the additional 16 data signals.

dylad · 2023-07-28T18:43:19Z

@gschorcht Sorry I don't have this one, I just had a look at my ST boards.
Best I can do is nucleo-F746ZG but I don't know if it will help you.

gschorcht · 2023-07-28T22:10:39Z

Best I can do is nucleo-F746ZG but I don't know if it will help you.

Hm, too bad. Nucleo boards do not have external RAM. I have a stm32f746g-disco board on which I could test the FMC peripheral with SDRAM and 16-bit data bus.

gschorcht · 2023-08-23T21:18:05Z

I ordered a stmf769i-disco board and tested the FMC with 32-bit data bus width. It works as expected see #19851 (comment).
