As for issue 1354 <https://github.com/apache/incubator-nuttx/issues/1354>, made the PR 1370 <https://github.com/apache/incubator-nuttx/pull/1370>. пт, 3 июл. 2020 г. в 16:26, Oleg Evseev <ev.m...@gmail.com>: > Hi, Alan. > > Thanks for the feedback. > > Found out that I'm still get DEBUGASSERT(pholder != NULL) in function > nxsem_allocholder in file semaphore/sem_holder.c after > DEBUGASSERT(sem->semcount<SEM_VALUE_MAX) fix, so it seems that they are not > related. > I'm trying to investigate this. > > пт, 3 июл. 2020 г. в 15:47, Alan Carvalho de Assis <acas...@gmail.com>: > >> Hi Oleg, >> >> I just responded your issue. >> >> I hope to have shed some light there. >> >> BR, >> >> Alan >> >> On 7/3/20, Oleg Evseev <ev.m...@gmail.com> wrote: >> > Regarding to can driver, from some moment I started getting >> > DEBUGASSERT(sem->semcount<SEM_VALUE_MAX) >> > in sem_post.c.
