Hello @pooja ,

Sorry for the late reply. Is the Ux_Device_CDC_ACM still not working?

Could you please add these code lines into the .ld file as detailed in readme:

._threadx_heap :
 {
 . = ALIGN(8);
 __RAM_segment_used_end__ = .;
 . = . + 64K;
 . = ALIGN(8);
 } >RAM_D1 AT> RAM_D1

Also, try to use the last STM32Cube_FW_H5_V1.1.1 package.

Please let me know if the issue is solved or not.

Thank you.
