Hello everyone.

While progress project, problem happened.

Talk about my project.

Give some command by 8051 controllers in MPC860.

Then, 8051 controllers are ordered and give again data that correspond
to the command to MPC860.

Then, 8051 controllers are ordered.

Give again data that correspond to the command later to MPC860.

Show data by console to confirm this data.

By the way, data is lost if execute code.

Can confirm datum of 5 ~ 6 of 7 data in console.

This project must not loss data.

Is no there solution method?

Sauce is as following.
......

#define buf 30

.......

void open_tty(void)
{
fdtyCo0 = open("/tyCo/0", 0x0202, 0); /* open the R/W mode */
fdtyCo1 = open("/tyCo/1", 0x0202, 0); /* open the R/W mode */
}
........
void aqsit_css(void)
{
unsigned char adcs_cmd[5] = {0x37,0x36,0x35,0x34,0x33}, /* css =
0xe0*/
adcs_tlm[buf];
int nread;

write(fdtyCo1, adcs_cmd, 5);

nread = read(fdtyCo1, adcs_tlm, sizeof(adcs_tlm));

write(fdtyCo0, adcs_tlm, sizeof(adcs_tlm));
}
......
void aqsit(void)
{
open_tty();
do{
aqsit_css();
}while(1);
}

Beam rate is 9600, tyCo0 is console and tyCo1 connected with 8051
controllers.
