RP2040 and tinyUSB and RT-Thread not working

Created at 2024-01-18 13:06:45

Dear all,

I like to use the RP2040 Raspi Pico, with RT-Thread standard and tinyUSB. I use scons --menuconfig to enable tinyUSB, set it to CDC, and select the "build example" item.

Compile, flash, but no USB-Uart or any serial device on the computer. Try it on Windows 10 and Ubuntu 22.

Is tinyUSB and RT-Thread and RP2040 working together? Did I forgot something?

What is the RT-Thread kernel version you are using?

Dear rbbbb,

I downloaded the latest version from https://github.com/RT-Thread/rt-thread 2 days ago.

In the rt_thread/rt-thread/ChangeLog.md, it says V5.0.2

I am still very new to RT-Thread. It seems, I forgot "pkgs --update" after selecting tinyUSB in menuconfig. So I did the update, then start scons again.
Give a lot of error messages:

I got some progress. There seem to be some gcc or/and C99 problems with the TinyUSB package. I am now able to compile, after doing the following hacks:

  • Disable the static_assert() calls in

/home/micha/rt_thread/rt-thread/bsp/raspberry-pico/packages/raspberrypi-pico-sdk-latest/src/rp2040/hardware_structs/include/hardware/structs/usb.h
(see also here: https://github.com/raspberrypi/pico-sdk/issues/339)

Handle GCC different from other compilers:
rt-thread/bsp/raspberry-pico/packages/raspberrypi-pico-sdk-latest/src/rp2_common/hardware_base/include/hardware/address_mapped.h

ifdef GNUC

#define hw_set_alias(p) ((__typeof__(p))hw_set_alias_untyped(p))
#define hw_clear_alias(p) ((__typeof__(p))hw_clear_alias_untyped(p))
#define hw_xor_alias(p) ((__typeof__(p))hw_xor_alias_untyped(p))
#define xip_noalloc_alias(p) ((__typeof__(p))xip_noalloc_alias_untyped(p))
#define xip_nocache_alias(p) ((__typeof__(p))xip_nocache_alias_untyped(p))
#define xip_nocache_noalloc_alias(p) ((__typeof__(p))xip_nocache_noalloc_alias_untyped(p))

else

#define hw_set_alias(p) ((typeof(p))hw_set_alias_untyped(p))
#define hw_clear_alias(p) ((typeof(p))hw_clear_alias_untyped(p))
#define hw_xor_alias(p) ((typeof(p))hw_xor_alias_untyped(p))
#define xip_noalloc_alias(p) ((typeof(p))xip_noalloc_alias_untyped(p))
#define xip_nocache_alias(p) ((typeof(p))xip_nocache_alias_untyped(p))
#define xip_nocache_noalloc_alias(p) ((typeof(p))xip_nocache_noalloc_alias_untyped(p))

endif

This is just a dirty hack, but at least, it compiles. Maybe the TinyUSB package maintainer set some flags, that the GCC/C99 problem with Pico(RP2040) get fixed.
