Hello,
Has any of you experienced occasional RTX 4.05 startup failures (data aborts during task creation) ?
Thanks in advance
Stuart, all,
My controller with RTX data in internal RAM started up correctly after 20 minutes without power. This is a good sign.
Tamir,
That is interesting, still if this is a problem with RTX 4.05 I am not sure how they are going to duplicate it.
It is strangely reassuring to know that I am not the only one with issues with RTX 4.05 especially as both of us were using external RAM.
Do you make any ISR calls that write to the new FIFO? I found that if I commented these out, RTX 4.05 worked in my external PSRAM, it was only when these functions were called did the system crash. (these calls seemed to work fine in RTX 4.00)

Stuart,
Thanks for your reply. I am not quite reassured actually...:-) My program never got that far; so no events were set from ISR to tasks - of that I am sure. It happened while setting up stack space for tasks. I just don't understand what is happening - the source looks OK at first glance. Also, both controllers (the one that suffered from it and the one that did not) use the same hardware design (copy-paste). yet one of them (multiple units) crashes with a regular pattern, the other not. weird weird weird. but moving all the ZI, RW data to internal RAM seems to have "solved" it.
