What happened ?
I am using TinyUSB as a HOST in a noisy environment and sometimes I need to reset the USB bus. To do this I call "hcd_init(0)" as part of the reset process.
Previously in TinyUSB version 0.13.0, this wasn't an issue and it allowed me to do this without crashing.
After this was added in TinyUSB 0.14.0,
rp2040: use shared IRQ handlers, so user can also hook the USB IRQ by @kilograham in #1519
it crashes on a hard_assert because of the call to "irq_add_shared_handler()" which was previously "irq_set_exclusive_handler()".
I believe the reason it is crashing is that it is exceeding PICO_MAX_SHARED_IRQ_HANDLERS.
Perhaps irq_remove_handler() should be called first?
How to reproduce ?
I added something like this to my code to confirm it crashed,
for(uint8_t x = 0; x < 20; x++ )
{
printf("calling hcd_init %d\r\n", x);
vTaskDelay(100);
hcd_init(0);
}
Debug Log as txt file
calling hcd_init 1
calling hcd_init 2
calling hcd_init 3
