RP2350: `rom_reboot` fails if `delay_ms` is set to 0

It seems like there is a bug when calling `rom_reboot` with `delay_ms` set to 0. If called with `delay_ms = 0` the function returns with `BOOTROM_OK` and does not reboot at all. Any value greater than 0 for `delay_ms` seems to work and the watchdog reset happens. Following code is expected to enter `BOOTSEL` mode after calling `rom_reboot`, however this does not happen. Instead, the LED flashes at 1/2 Hz and some text is printed to the console: ```c #include <stdint.h> #include <stdio.h> #include <pico/stdlib.h> #include <pico/bootrom.h> #include <boot/picoboot_constants.h> #include <hardware/gpio.h> #define GPIO_LED 25 int main(void) { stdio_init_all(); gpio_init( GPIO_LED); gpio_put( GPIO_LED, true); gpio_set_dir( GPIO_LED, true); // Wait for USB sleep_ms(2000); printf("rom_reboot: test bug\n"); // == 0 -> no reboot // != 0 -> reboot after delay_ms uint32_t delay_ms = 0; int rom_reboot_ret = rom_reboot(REBOOT2_FLAG_REBOOT_TYPE_BOOTSEL, delay_ms, 0, 0); // reports BOOTROM_OK printf("rom_reboot: %u\n", rom_reboot_ret); while (true) { sleep_ms(1000); gpio_xor_mask(1 << GPIO_LED); printf("This should not be output to the console\n"); } } ```
