Esp32c3 and spi2 date version problem

[BugSimpson]

Hello,
Can someone explain to me why I can't read a register from the SPI2 controller? No matter which register is read, a 0 is always returned. I read the date register from the gpio controller and the value matches.

anyone have an idea?

Make sure to take the peripheral out of reset and un-clockgate it.

you mean the "SYSTEM_SPI2_CLK_EN" Bit? (see Pic.)
it is enabled..

perfect, thank you.
It was really because the Spi2 unit was in a reset state, which according to the data sheet it shouldn't be in a reset state
