TDA2EXEVM: Integrating Mailbox Communication with SYS/BIOS configuration on EVE Processors

Manavi H V

Part Number: TDA2EXEVM

Hi ,

I'm working on establishing the mailbox communication between EVE processors with SYS/BIOS configuration. Integrating the mailbox example which is given under startarware.
Trying to send the message from EVE1 to EVE2 , problem here is we are unable to receive the message on EVE2.

NOTE: we are able to establish the mailbox communication between EVE1 and EVE2 in bare-metal application

but communication is not working when we tried to do the same with SYS/BIOS configuration of Processor Vision SDK.

FYI, I'm including the Interrupt Service Table in C code as below:

extern interrupt void NMI_IRQ(void);

extern interrupt void SWI_IRQ(void);
extern interrupt void INTH_IRQ4(void);
extern interrupt void INTH_IRQ5(void);
extern interrupt void INTH_IRQ6(void);
extern interrupt void INTH_IRQ7(void);
extern interrupt void INTH_IRQ8(void);
extern interrupt void INTH_IRQ9(void);
extern interrupt void INTH_IRQ10(void);
extern interrupt void INTH_IRQ11(void);
extern interrupt void INTH_IRQ12(void);
extern interrupt void INTH_IRQ13(void);
extern interrupt void INTH_IRQ14(void);
extern interrupt void INTH_IRQ15(void);

#pragma DATA_SECTION (ist_table, ".intvecs");
typedef interrupt void(*inthandler)(void);

volatile inthandler ist_table[17] =
{
&NMI_IRQ,
&SWI_IRQ,
&INTH_IRQ4,
&INTH_IRQ5,
&INTH_IRQ6,
&INTH_IRQ7,
&INTH_IRQ8,
&INTH_IRQ9,
&INTH_IRQ10,
&INTH_IRQ11,
&INTH_IRQ12,
&INTH_IRQ13,
&INTH_IRQ14,
&INTH_IRQ15

};

Please let us know if we are missing any configuration to enable mailbox with SYS/BIOS.

Hi,

You can refer to IPC lite which is also bare-metal IPC used in SYSBIOS with Vision SDK.

Hi Stanley,

Thank you for the response.
As you suggested I tried to use IPC lite with SYS/BIOS to communicate between EVE1 to EVE2 processor.
I'm facing the binary crash issue while sending the message on EVE1 to EVE2.

NOTE: one behavior I observed is that I'm able to establish the communication between EVE1 to EVE2 if I disable eveMmuConfig() function in configuration file of EVE processors. I'm using 0x40081000U as a base address on EVE1 and EVE2 to configure MMU. Is this base address should be different on each EVE processor ?

Below are the steps I'm following at sender and receiver side.
Receiver's sequence
1. IPCLib_interruptSetDefaultInitPrm()
2. Change params as required
3. IPCLib_interruptInit() - with valid params
4. IPCLib_interruptRegisterEvent() - with valid callback function

Sender's sequence
1. IPCLib_interruptSetDefaultInitPrm()
2. Change params as required
3. IPCLib_interruptInit() - with valid params
4. IPCLib_interruptRegisterEvent() - with valid callback function
5. IPCLib_interruptSendEvent() - with valid payload and event id

here at sender sequence execution is crashing when it executes

HW_RD_REG32(baseAddr+MAILBOX_MESSAGE(queueId)) function in IPCLib_interruptSendEvent() step( 5th step).

I have attached the EVE1 and EVE2 source file.

Please let me know how eveMmuConfig() function is effecting for the communication and also if I'm missing any steps to enable IPC_LIB with SYS/BIOS configuration.

Hi Stanley,

The above communication between EVE1 and EVE2 with IPC lite is resolved after adding 0x42000000 address in TTB buffer entry table of MMU config function.

Now the problem is,
I'm unable to establish the communicate between EVE1 to EVE2 if I use "SR1_FRAME_BUFFER_MEM" shared region between EVE1 and EVE2 .

NOTE: I'm able to establish the communication between EVE1 to EVE2 if I disable the usage of shared region that is "SR1_FRAME_BUFFER_MEM : org = 0x8a783000, len = 0x1537d000" .

here all the sequence at sender and receiver side is executing successfully. EVE1 is sending the message to EVE2 but at EVE2 side interrupt call back function is not getting invoked.

I have attached the EVE1 and EVE2 source file.

Please let me know how the usage of shared region "SR1_FRAME_BUFFER_MEM" is effecting for the communication and also if I'm missing any steps to enable shared region with IPC_LIB in SYS/BIOS configuration.

Hi Manavi,

I think the cache is enabled in the SR1_FRAME_BUFFER_MEM region.

You will need to perform cache maintenance routines to maintain the cache coherence between EVE1 and EVE2.
