Summary: hal_interrupt_mask() interrupt lost
Product: eCos
Version: CVS
Platform: All
OS/Version: Cortex-M
Status: UNCONFIRMED
Severity: enhancement
Priority: low
Component: HAL
AssignedTo: unassigned@bugs.ecos.sourceware.org
ReportedBy: uholeschak@bihl-wiedemann.de
CC: ecos-bugs@ecos.sourceware.org
Class: Advice Request
The function hal_interrupt_mask() masks the interrupt in the NVIC and also
disables the interrupt source by calling HAL_VAR_INTERRUPT_MASK.
If i understand the documentation of cyg_interrupt_mask() and
cyg_interrupt_unmask() correctly, the function pair is intended to be a
possibility to mask the interrupt in critical sections (and not to disable the
interrupt).
The problem is now, that the call of HAL_VAR_INTERRUPT_MASK() disables the
interrupt source, so every interrupt in the mask period is lost.
Perhaps it would be a solution not to call HAL_VAR_INTERRUPT_MASK() from
hal_interrupt_mask().
If the user wants to enable the interrupt source he could call this function
directly ...
