I have a question about the external flash loader.

hello

I am developing an external flash loader with stm32g070.

There is something I don't understand about this.

1. Should I use only the internal clock for external flash loader, not the external crystal?

2. Can't I use the interrupt?

Please reply to the above two questions.

Thank you.

You can run at whatever speed you find convenient, if you want to use the internal or external sources, or with PLL you can bring those up. The Write and Erase won't get any faster, the read and other IO and memory operations will.

You shouldn't need to be using interrupts, you can use other methods to mark time without using the SysTick. The HAL Tick methods are abstracted, so don't need to be using interrupts.

It is recommended that you test read, write and erase functionality in a test application that you can debug.
