I wrote a BootLoader program. and a APP
program
I downloaded the BootLoader to the 0x0 address in Flash By UDE 4.8.
I downloaded the App to the 0x18000 address in Flash By UDE 4.8.
//code 1:
componentsInit();
irqIsrEnable();SPCSetRunMode(SPC5_RUNMODE_DRUN);
irqIsrDisable();
asm volatile (''e_lis %r3, 0x00018008@h \t\n''
''e_or2i %r3, 0x00018008@l \t\n'' ''mtctr %r3 \t\n'' ''se_bctrl'');//APP：
componentsInit(); irqIsrEnable(); for ( ; ; ) { pal_lld_togglepad(PORT_C, PC_LED8); osalThreadDelayMilliseconds(1000); }Everything is OK.
But ,If i am use CAN in the Bootload .when the APP run to irqIsrEnable
.it will be enter
_unhandled_irq function//code 2:
componentsInit();
irqIsrEnable();can_lld_start(&CAND1,&can_config_cfg0);
SPCSetRunMode(SPC5_RUNMODE_DRUN);
irqIsrDisable();
asm volatile (''e_lis %r3, 0x00018008@h \t\n''
''e_or2i %r3, 0x00018008@l \t\n''''mtctr %r3 \t\n''''se_bctrl'');//APP：
componentsInit();irqIsrEnable();
for ( ; ; ){ pal_lld_togglepad(PORT_C, PC_LED8); osalThreadDelayMilliseconds(1000);}I think that before the jump to close the CAN, APP implementation irqIsrEnable will continue to run.but i try call can_lld_stop.andt jump to APP ,it doesn't work..
pls help me !
