Matteo Concas commented on a discussion on bsps/shared/grlib/1553/b1553rt.c: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/273#note_113963 > tsw = READ_DMA(&rt->mem[tx*0x3E0+suba]); > > /* Build Message Information Word (B1553BRM-style) */ > - miw = (wc<<11) | (tsw&RT_TSW_BUS)>>4 | !(tsw&RT_TSW_OK)>>7 | > (tsw&RT_TSW_ILL)>>5 | The `RT_TSW_OK` field is set to 1 if there was no error. The Message Error (ME) field indicates an error and must be set to 0 if there was no error so the result of `tsw&RT_TSW_OK` must be negated. Another way to do this would be ``` ~(tsw&RT_TSW_OK)>>7 & (1<<7) ``` But I don't think this is be cleaner than the current fix. -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/273#note_113963 You're receiving this email because of your account on gitlab.rtems.org.
