Part Number:CC3100
Hello Support Team,
we have identified an issue with large data transfer (send via Wifi).
This issue occurs in infrastructure mode (STA) and also in Adhoc mode while:
- Transmits large file (>1MB) in 1024 Byte chunks over socket
- then an 0 length IQR occurs between the blocks which are cleared by the driver
- an interrupt occurs during DMA transfer and cannot served
- chip hangs afterwards, not responding to any commands
How can an IRQ be initiated by the CC3100 an no reason for the interrupt will be provided - raw data in this case is 0xBF 0xDC 0xCD 0xAB 0x63 0x00 0x04 0x00 0x37 0x00 0x0B 0x00.
As far as we have analyzed it is nor clear how the flow control during transmit will be reported back to the Host controller.
Feedback urgently required!
