Function embassy_rp::rom_data::flash_enter_cmd_xip
source · pub unsafe extern "C" fn flash_enter_cmd_xip()Expand description
Configure the QMI to generate a standard 03h serial read command, with 24 address bits, upon each XIP access.
This is a slow XIP configuration, but is widely supported. CLKDIV is set to 12. The debugger may call this function to ensure that flash is readable following a program/erase operation.
Note that the same setup is performed by flash_exit_xip(), and the RP2350 flash program/erase functions do not leave XIP in an inaccessible state, so calls to this function are largely redundant. It is provided for compatibility with RP2040.
Supported architectures: ARM-S, RISC-V
§Safety
This is a low-level C function. It may be difficult to call safely from Rust. If in doubt, check the rp235x datasheet for details and do your own safety evaluation.
