Hi,
Even I tried the similar method but the same issue.
I was trying to configure the SW4 - 0 as the edge triggered interrupt
source. On DM6437 EVM it is connected to GP4 (according to Technical
Reference Manual and Schematic). From TMS320DM643x DMP General-Purpose
Input/Output (GPIO)(spru988A) guide on page -14 we found that the DSP
Interrupt number is 68 for GP4.We have configured the HWI_INT4 in
DSP/BIOS and entered "68" in interrupt selection number field and a ISR
handler function with Interrupt Mask as 'all'. But the control is never
coming into the ISR????
Please help.
Rgds,
Kumar GVS

Subject: IRQ in DM6437
Hi,
I tried to configure the GPIO 29 as an interrupt signal to the DM6437
(DSP/BIOS as the OS.) But this interrupt is not getting into the ISR I
have written.
But the Interrupt status register is showing a pending interrupt for the
GP[29]. I feel this may be an issue with configuring DSP/BIOS for the
interrupt. Can anyone help me to solve out this issue.
Regards,
Rakesh Jagota
