Hi,I'm trying to setup this new RAM chips on STM32H735 in OSPI/HyperRAM mode. The HW connection is the same as on ST STM32H735 devkit. I found a driver for similar chip S70KL1281 but there are some differences, e.g. in latencies, but generally S70KL1...

I updated STM32CubeMX 6.9 to 6.11.0 and migrated my previously configured project (for stm32h735) to new version and now I have a problem that everytime I re-generate the code the compiler complains about missing syscalls.c, sysmem.c files. This file...

Hi, I assigned all used GPIOs to desired functions except the PC2 at ball M1. The datasheet seems doesn't indicate this pin would be something special. I just need SPI2_MISO there but MX doesn't allow select anything, all choices are off just the Res...

Yes I did take a care about QSPI length matching but on such relative low frequencies it doesn't matter much... Even I tried lowering QSPI clock frequency and it has no effect.

Hi, sorry, I'm currently working on another PCB design project so I didn't debug it further. But I got some sample code from Infineon for this memory chip and a bit different STM32 MCU that is claimed to work. I hope I'll have a time to try it out so...

No, refresh settings didn't have any effect on this issue. Currently I'm working on other project so I'll return to this later. I also asked on Infineon forum where they only suggested a change of latency 6->7 that I already did...

Any chance that some engineer from ST could try the new memory S70KL1282 on the discovery kit?I think that they will be forced to upgrade anyway as the current part is EoL and will be no longer available. Except they bought a huge amount of old chips...

I tried to vary hospi2.Init.Refresh with different values: 50, 100, 200, 300, 500, 1000 and it doesn't have any effect on 8-byte data write offset. I think it doesn't matter anyway because I write only a short data block that's transfered many times ...

Setting up HyperRAM S70KL1282 with STM32H735 issues

After migrating project from CubeMX 6.9 to 6.11.0 two sys.C-files was deleted but forced in Makefile

STM32CubeMX cannot assign GPIO at pin PC2 on STM32H735IGK6 MCU (UFGA176+25)
