Tool/software:
Currently my set up is we have 1 UDMA Instance for the OSPI that use UDMA_INST_ID_BCDMA_0 and I want to add another udma instance for the uart, namely UDMA_INST_ID_PKTDMA_0.
But the second "Udma_chOpen()" is failed because the "drvHandleInt->drvInitDone" is not done yet. If I debug this function, it runs to "Udma_chPair()" and return fail.
So I test it on the uart dma echo example on the Evaluation Module and observed that if I add another instance to the code (by add it in example.syscfg):
/* UDMA driver instance object */
Udma_DrvObject gUdmaDrvObj[CONFIG_UDMA_NUM_INSTANCES];
/* UDMA driver instance init params */
static Udma_InitPrms gUdmaInitPrms[CONFIG_UDMA_NUM_INSTANCES] =
{
{
.instId = UDMA_INST_ID_PKTDMA_0,
.skipGlobalEventReg = FALSE,
.virtToPhyFxn = Udma_defaultVirtToPhyFxn,
.phyToVirtFxn = Udma_defaultPhyToVirtFxn,
},
{
.instId = UDMA_INST_ID_BCDMA_0,
.skipGlobalEventReg = FALSE,
.virtToPhyFxn = Udma_defaultVirtToPhyFxn,
.phyToVirtFxn = Udma_defaultPhyToVirtFxn,
},
};
CONFIG_UDMA_NUM_INSTANCES also increased to 2. But the FW also stopped at "UART_udmaInitRxCh()" in "Udma_chOpen()" just like in my app above without actually using the 2nd udma yet.
So my question is how could I use 2 instance at the same time, specially 1 for Ospi and 1 for uart (with pdma).
Is it possible to use it that way?
