Silicium revision and MQX

I have a problem since I try to update a project with the last MQX version, on a Kintetis K60N512 target.


The project doesn't run with new silicium version 4N22D... With an older, 4N30D, there is no problems.


Before running the main task, in the asm parts, MQX go in an infinite loop (dispatch.S, line 462) because it can not find any task in the fisrt call of _pend_svc (dispatch.s, line 400).

The creation of the idle task seems to be juste after (...), in dispatch.S, line 315.

In step by step, with a 4N30D mask, the MQX is OK, no stop in infinite loop et go normally in my app.


The big difference seems to be in _bsp_enable_card (init_bsp.c. ) between MQX 3.8.1 and versions.


I think there is no relation with my app, because MQX has not jump into it at this moment.


Any ideas ?
