Forum Post: Issue while using Queued SPI at host micro with CC3000

Hello,

I am using Freescale host micro (that supports Queued SPI) with TiWi-SL module.


When I do not use queued SPI functionality then it works fine consistently. Means I just Tx and Rx one byte at a time.

But when I use queued SPI functionality and fill transmit queue with max 16 bytes and then start TX/RX, CC3000 seems to stop responding after some time.

Please find attached logs:

teraterm_QSPI_1.log => Log1 when QSPI is used. Stops after some time.
teraterm_QSPI_2.log => Log2 when QSPI is used. Stops after some time.

teraterm_SingleByte_SPI_1.log => When QSPI functionality is not used. Just Tx/Rx one byte at a time. No issue.

Current application establishes the connection and starts receiving data continuously, untill user stops it.

Please evaluate the logs and suggest. Could there be any limitation from CC3000 side when I use QSPI?

Thanks and Regards,

Manish K
