What SDIO interface chip (with a 3.3V host side) are people using these days? The IP4856CX25 (used on the H7 Eval board) is NRND, and I can't seem to find an SDIO interface chip that supports a 3.3V host side. What part should I use for a 3.3V H7 des...

OK I found the reason -- I had silicon rev Y selected (has max core clock speed of 400 MHz) instead of V (supports max core clock speed of 480 MHz). It was non-obvious to me what the problem was, perhaps the reason can be displayed when you hover the...

Attached is the ioc file that exhibits the issue.

I'm seeing incorrect behavior in the Clock Configuration screen. It is flagging valid values as being out of range (STM32H743XIH6). Is anyone else seeing this? If I save and re-start CubeMX, I still see the same problem.

When we built the last spin of our board, we were unable to find any TXS0206 parts (or anything similar), so I removed the TXS0206 from the design, and I drive the SD Card interface directly from the STM32H7. I am not 100% sure we needed SDR104 now, ...

My current plan is to utilize a TXS0206: https://www.ti.com/lit/ds/symlink/txs0206.pdfAnd I'll add a voltage regulator to VCCB that I can manually switch from the MCU via SD_LDO_SEL.-Chris

Can the ROM bootloader in the STM32H7 be configured to use the high speed USB interface instead of the full speed USB interface?
