K81 blhost spi error

[kaustubhkulkarn]

Hello,

I am working on the K81. I am using blhost with spi (run mode with 4Mbps) to write .sb file to the QSPI memory. But I am getting following error.

Inject command 'receive-sb-file'
Preparing to send 345760 (0x546a0) bytes to the target.
Successful generic response to command 'receive-sb-file'
(1/1)0%Error: read_start_byte() timeout after 10.037 seconds
Data phase write aborted by status 0x5 kStatus_Timeout
Error: read_start_byte() timeout after 10.025 seconds
Response status = 10004 (0x2714) No response packet from target device.
Wrote 672 of 345760 bytes.

Could you please help me with this.

Thank you.

Hi,

I'm not sure if you connect your system correctly. Please review <Kinetis blhost User's Guide.pdf> for detail. In Appendix C, it describes how to download code by blhost if you want to use SPI.
