I did set it to 0xebf for 921600: this is my psr file , actually I wirte this psr file according to the value I used in CSR bchs stack's boot_strap , these setting in bchs's stack can make the chip working normally : // PSKEY_ANA_FREQ &01fe = 0FA0 // PSKEY_UART_BAUD_RATE &01be = 0EBF // PSKEY_UART_SEQ_WINSIZE &0407 = 0006 // BDADDR &0001 = 1122 3344 5566 7788 // PCM_CONFIG32 &01b3 = 0080 0906 // PCM_FORMAT &01b6 = 0060 // MAP_SCO_PCM &01ab = 0001 // MAP_SCO_CODEC &01b0 = 0000 // CODEC_PIO &01b9 = 000b // ANA_FTRIM &01f6 = 0025 > I try to use following cmd to see whether the cmd is write in to the chip, > but : > > ~ # bccmd -t bcsp -d /dev/ttyS1 psget -s 0x0 0x1be > UART Baud rate: 0x0000 (0) > ~ # > ~ # bccmd -t bcsp -d /dev/ttyS1 psset -s 0x0 0x1be 0x0ebf > ~ # > ~ # bccmd -t bcsp -d /dev/ttyS1 psget -s 0x0 0x1be > UART Baud rate: 0x0000 (0) > > seems chip just reset it self between two bccmd with bcsp protocol, and lost > everything write to it. > Yes, I had the same behaviour, and only if I use -r with first bccmd > things worked.

Thanks god, I finally find something that work the same way as you 8 ) though this is also not so promising... I had plan to modify the bccmd to set the pskey and read the pskey at one time, to see what make the bccmd not working for second time. Maybe it help to understand the stack behavior. Thanks.
