dear supporter,
I use McSPI1 int nimber 125, but it can not input interrupt ISR, need other setting?
status = request_irq(125, spi_rx_full_isr, 0, "spi_rx_full_irq", mcspi);
// Enable IRQ on RX1 full
irq_enable = 0x00000000;
MOD_REG_BIT(irq_enable, OMAP2_MCSPI_IRQ_RX1_FULL_ENABLE, 1);
mcspi_write_reg(mcspi->master, OMAP2_MCSPI_IRQENABLE, irq_enable);
see the value of register INTC_ITR3.Value INTC_ITR3 = 20000000. Interrupt is set, but the value of INTC_MIR3 = FFFFDFFA, so the interrupt system is not working.
is it SDK bug?
