Hello,
some time ago I wanted to use EoE with the NDK which was a success. At this point of the project there was an issue observeable which seems not to be intended.
I'm using SSC Version 5.12. I'm using the ETG stack based on the ICEv2-Board configuration.
It seems, that receiving and sending via EoE is not supported if done in different tasks. The global variable psWriteMbx defind in the ETG file "mailbox.h" is used in both sending and receiving frames. In the sample EoE application sending and receiving is done in the same task, in most applications this is not the case.
It is possible, that the sample crashes, if another task is created which sends data using EOE_SendFrameRequest(). Usally this problem can be solved by using a lesser priority for the sending task (seems to be the solution for the generic ETG task) than for the ETG MAIN task. But in the TI implmentation the funcion "MBX_CheckAndCopyMailbox" allocates a Write Mailbox, calls HW_EscReadByte() which leads to a signal wait. Then the sending task can call EOE_SendFrameRequest->SendFragment()->MBX_MailboxSendReq()->MBX_CopyToSendMailbox(), which is clearing spWriteMbx. After the Main tasks continius using an invlid mailbox pointer.
Is this a known issue, do you know any walkaround or did I use a wrong sending function for EoE - if this is the case, which is the correct one?
Thank you very much.
