How can I measure sd card default speed?

2023-05-15
hi every one ~~!! I am using STM32h743bit6.​How can I measure sd card default speed?​SDIO_CLK? SDIO_CMD??​

How to measure sdmmc clock (200Mhz) of stm32h743BIT6?

Hi guysI am trying to measure the sdmmc clock of stm32h743BIT6. Which line should I draw to see

I want to measure the speed of reading a binary file (image) in SDCARD.

Hi!!! ​I am using STM32H743BIT6 MCU and I want to measure the speed of reading a binary file (image) in SDCARD.​SDMMC1 is set and SD 4 wire bus is set.​On which pin should I take the measurement on the MCU? Also, the unit of speed is (Mbyte/s). Is it...

I want to know about the GPIO max speed environment. And is the GPIO max frequency measurable according to the datasheet?

I am using STM32H743Bit6.Checking GPIO maximum frequency.Among them, in output mode 11, the maximum frequency of 220Mhz was confirmed in the third environment.What does the 'c' in conditions mean where?

I would like to know about the 4 GPIO speed settings on the STM32H743BIt6. And is it possible to measure the system clock 400Mhz from the MCO2 pin output terminal?
