P4080: Unable to get the LBC interrupts in SDK 1.7

ajayjoshi · ‎02-26-2015

Hi,

We are using the P4080 based board for one of our projects using the SDK 1.7. We need to use the interrupts for the nand flash and SPI. But when we enable the interrupts in the dts files, we do not seem to get any interrupt on the common LBC interrupt handler code in the fsl_lbc.c. It works in 1.3. Do we need take anything specific for 1.7 sdk for enabling this interrupt ?

Regards,

Ajay

What do you mean by enabling the interrupts in the dts files? The eLBC and eSPI interrupts should already be present in the SDK device tree. What are you doing that should be triggering an interrupt but isn't? Have you verified through /proc/interrupts that the interrupt is being registered properly? Do you see the interrupt pending or masked in the eLBC registers?
