<table cellspacing='0' cellpadding='0' border='0' ><tr><td style='font: inherit;'>Hi all,<br> 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..<br><br> If I run same Interrupt Enabled U-Boot from Flash. Interrupts are handling properly.<br>Here Interrupts Enabling means I defined CONFIG_USE_IRQ in my configuration header file and Unmasked some specific interrupt.<br><br> 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.<br><br> 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.<br><br> Can Anyone Explain me briefly what is happening when this macro is defined.<br> Please suggest me as soon as possible..........<br><br>Thanks & Regards,<br>Chaitanya.<br><br><br><br><br><br><br><br></td></tr></table><br>
