| Hi all, I Enable Interrupt support (by defining CONFIG_USE_IRQ) and unmasked some specific Interrupt in U-Boot for omap5912 . In Flash, U-boot without interrupt Support has been flashed. When Iam Running Interrupt Enabled U-Boot from RAM (with go command) , When Interrupt Comes its just Hanging... Iam not getting Where control is jumping.. If I run same Interrupt Enabled U-Boot from Flash. Interrupts are handling properly. Here Interrupts Enabling means I defined CONFIG_USE_IRQ in my configuration header file and Unmasked some specific interrupt. If I Enable Interrupt support using( CONFIG_USE_IRQ ) and not unmasking any interrupt in U-Boot , I flashed this U-Boot to NOR-Flash. and In another U-Boot Iam Enabling Interrupt Support and unmasking my Specific interrupt. Now Iam running this U-Boot from RAM. Now Interrupts are handled properly. The Major Change I observed is with CONFIG_USE_IRQ macro, If and only if this macro is defined Flashed U-Boot, Interrupts are Handling Properly. Can Anyone Explain me briefly what is happening when this macro is defined. Please suggest me as soon as possible.......... Thanks & Regards, Chaitanya. |
