[ECOS] eCos application error- ASSERT FAIL : invalid priority

[ECOS] eCos application error- ASSERT FAIL : invalid priority

[Rohit Pandita]

Hi all,
Have a couple of questions,

1. While trying to execute/debug an eCos application in RAM I get ASSERT 
FAIL: var_intr.h[2343]: void cyg_hal_interrupt_set_level() : Invalid 
priority.
Has it got anything to do with with eCos Kernel scheduler config? Any 
solutions.

2. My application requires I/O through both serial ports on the target 
(Phy555). Is this permissible, given that RedBoot uses the serial ports 
for CLI and debug/diagnostic purposes? If not, what changes would be 
necessary.

Thanks in advance,

Rohit

What priority are you passing? What priorities are valid?

You could use Ethernet for Redboot/gdb so leaving the second ethernet
port free. Otherwise just don't use diag_printf and gdb and redboot
will keep quiet when your application is running.
