Hi Sanja
Thanks for your instruction !!
I found it behavior on my board a little different from you :
If I using -r in the bccmd:
~ # bccmd -t bcsp -d /dev/ttyS1 psload -r csr.psr
Loading PSKEY_ANA_FREQ ... done
Loading PSKEY_UART_BAUDRATE ... done
Loading PSKEY_UART_SEQ_WINSIZE ... done
Loading PSKEY_BDADDR ... done
Loading PSKEY_PCM_CONFIG32 ... done
Loading PSKEY_PCM_FORMAT ... done
Loading PSKEY_HOSTIO_MAP_SCO_PCM ... done
Loading PSKEY_HOSTIO_MAP_SCO_CODEC ... done
Loading PSKEY_CODEC_PIO ... done
Loading PSKEY_ANA_FTRIM ... done
~ #
~ # hciattach -s 921600 /dev/ttyS1 bcsp 921600
BCSP initialization timed out
It won't work,
If I don't do reset at the same cmd, but instead do it seperately:
~ # bccmd -t bcsp -d /dev/ttyS1 psload csr.psr
Loading PSKEY_ANA_FREQ ... done
Loading PSKEY_UART_BAUDRATE ... done
Loading PSKEY_UART_SEQ_WINSIZE ... done
Loading PSKEY_BDADDR ... done
Loading PSKEY_PCM_CONFIG32 ... done
Loading PSKEY_PCM_FORMAT ... done
Loading PSKEY_HOSTIO_MAP_SCO_PCM ... done
Loading PSKEY_HOSTIO_MAP_SCO_CODEC ... done
Loading PSKEY_CODEC_PIO ... done
Loading PSKEY_ANA_FTRIM ... done
~ #
~ # bccmd -t bcsp -d /dev/ttyS1 warmreset
~ #
~ # hciattach -s 921600 /dev/ttyS1 bcsp 921600
~ #
~ # hciconfig hci0 up
~ #
Seems it can connect to the chip, but still, pskey don't set right , I can
read it out and see it's still the reset value ......
~ # bccmd psget -s 0x0 0x01be
UART Baud rate: 0x0000 (0)
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.
But if I set up the pskey use hci protocol after hciconfig up, it's ok. but
reset lost the connection:
~ # hciattach -s 38400 /dev/ttyS1 bcsp
~ #
~ # hciconfig hci0 up
~ #
~ # bccmd psget -s 0x0 0x1be
UART Baud rate: 0x0000 (0)
~ #
~ # bccmd psset -s 0x0 0x1be 0x01d8
~ #
~ # bccmd psget -s 0x0 0x1be
UART Baud rate: 0x01d8 (472)
~ # bccmd warmreset
~ # ~ # bcsp_recv: Error in BCSP hdr checksum
Sigh ... Do you have any idea what might be wrong for my operation ?
