Execute in flash

#if defined(CLK_200M_D)

SystemFlash_TrimLoad(FLASH_FRQ_50M_LVL);

The GPIO module is hung on the AHB bus

AHB bus clock configuration

The test procedure is as follows:

What the logic analyzer sees

analyze:

In principle, the IO speed should be much greater than 3MHz, and some features should not be enabled.

The IO speed should be much greater than 3MHz, and some features may not be enabled.

Why is it not opened?

Is the maximum and fastest flip speed of Yichuang ET6001IO also 50M?

Try running it in TCM memory

Executed in flash, probably cache is not enabled, you can enable it and try again

    SCB_EnableICache();
    SCB_EnableDCache();
