Hi,
I run rtems6 on my imx6ull board, just initialize a GPT timer to flash
a LED. I load rtems with barebox, after output some initialized messages,
system enters shell and stalls, interrupt(GPT timer, arch7 timer for tick) do
not happen again. Shell (connect to UART1,interrupt mode) still works, when I
type something, the LED flashes. It seems that system only responses to UART1
interrupt, and triggers the other interrupts respones. I remove wfi instruction
from idle task, system runs ok.
And when I replace barebox with uboot, everything seems OK. I think maybe some
initialized differences between barebox and uboot, but I haven't find
any clues that may influence WFI.
Any suggestion?
