  Hello,all,

  I have learned that the TCB_MAX_COUNT is the send queue's length. And the default value is 256.

  Now I am realizing relay function on SORA. So I want to increase the send queue's length.(eg. 512 or 1024).

  But when I modified the value and having a test. The driver is easily broken down.

  And, when I remain the default value(256) , the driver is working normally.

  After broken, the crash dump file is :

  ----------------------------------------------------------

   But I can't see the source code of __SoraHwTxUnsafeNoWait.

  So I want to ask if the current SDK1.1 support us to modify this TCB_MAX_COUNT value?

  Or how to fix this problem?

  Thanks a lot.
