Hi,
What is the maximum size for .bufsize in TI Mailbox? The maximum buffer length I need to send through the mailbox is 1033. But seems like the mailbox init function does not like the size, it crashes when I try to Mailbox_Construct() with those parameters. I think it's too big(?) because when I change the MAILBOX_SIZE to 16 instead of a large number, it works perfectly fine.
I am trying to implement the Ymodem transfer protocol using TI UART and Mailbox - which is why my buffer is so large. It needs to transport 1024 byte data packets.
Here are my mailbox size and buffer used:
#define MAILBOX_SIZE = 2000
uint8_t message[MAILBOX_SIZE];
Here are my mailbox parameters in my MailboxInit():
Mailbox_Params_init(&mboxParams);
Error_init(&eb);
uint32_t size = sizeof(Mailbox_MbxElem) + MAILBOX_SIZE;
Mailbox_construct(&mailboxStruct, size, MAILBOX_SIZE, &mboxParams, &eb); //1 message
mailboxHandle = Mailbox_handle(&mailboxStruct);
if (mailboxHandle == NULL)
{
return -1;
}
mboxParams.buf = message;
mboxParams.bufSize = size;
return 0;
Thank you.
