Hello,I am trying to use an H7 with USB OTG as host/device. Only 1 will be enabled at any given time. The issue is that with Cube, if I set the FS PHY to OTG/Dual_Role_Device, I get nothing but the IO set. Which is, obviously, the opposite of what I ...

Specifically I've noticed it with the octospi, but it's also impacted at least software requests.For example, my MDMA config has hmdma_octospi1_fifo_th.Instance = MDMA_Channel1; hmdma_octospi1_fifo_th.Init.TransferTriggerMode = MDMA_BUFFER_TRA...

Hello,I am interested in seeing the memory map of the H7A3. I have been able to find some information from the HAL drivers, but there is a lot missing. That table does not exist for the H7A3 in the reference manual, which is where the datasheet says ...

Hi @Amel NASRI ,I regret to inform you the memory map is incorrect. Table 6 lists 0x9000_0000-0x9FFF_FFFF as QUADSPI. The H7A3 does not contain a QUADSPI peripheral, but rather 2 OCTOSPI peripherals. The only mention of QUADSPI in RM0455 is this new...

Sure. I've attached an IOC that shows the issue for software and OCTOSPI requests. For me, the initializations look like:static void MX_MDMA_Init(void) { /* MDMA controller clock enable */ __HAL_RCC_MDMA_CLK_ENABLE(); /* Local variables */ ...

Hi, @Amel NASRI So those are the AHB peripheral addresses which are used for configuring the devices, but those have memory mapped functionality.For example, if you look at the OCTOSPI block diagram (Fig 135, page 867) you see it has 2 ports. The AH...

I'm usually fine with that to an extent. CubeMX is a good program overall for those big interfaces. But even the Cube(s) don't tell me what the memory map is. I have to go digging and hope it's in a HAL driver.

Yes. I am aware of those tables. However, not only do I strongly agree it needs to be presented as it is in the other manuals, it also is missing key information about memory mapped areas that don't fit in those categories. Such as the OctoSPI and GF...
