BOARD : OMAP-L138
TOOL : CCS v3.3
pspdrivers_01_30_00_06
dspbios : 5.33.06
rx_data() and tx_data() functions work well. but interrupt... not work.
this source is UART intialization. and picture below is Interrupt_init and dsp/bios setting.
I don't know what setting is missing.
echo program is ceated to test.
and picture below is register value (Observing through emulator)
before push 'a' button. +0x0000 : receiver buffer(RBR) / +0x0004 : interrupt enable(IER) / +0x0008 : interrupt identi( IIR) / +0x00014 : line status (LSR)
after push 'a' button. RBR, IIR, LSR is changed.
the problem is that after one operation the echo program is not opertated.
Give me advice....
Thank you~
