Tool/software: Code Composer Studio
Hello,
1- I'm trying to configure the Concerto Ethernet. I just import the enet_uip_m3 example in v210 of master core and tried to blink the led. I notice that after the uDMA configuration, I cannot blink, but before all works fine.
GPIOPinWrite(GPIO_PORTC_BASE, GPIO_PIN_7, 1);
GPIOPinWrite(GPIO_PORTC_BASE, GPIO_PIN_7, 0);
// Configure the DMA TX channel
uDMAChannelAttributeDisable(UDMA_CHANNEL_ETH0TX, UDMA_ATTR_ALL);
uDMAChannelControlSet(UDMA_CHANNEL_ETH0TX,
UDMA_SIZE_32 | UDMA_SRC_INC_32 |
UDMA_DST_INC_NONE | UDMA_ARB_8);
GPIOPinWrite(GPIO_PORTC_BASE, GPIO_PIN_7, 1);
GPIOPinWrite(GPIO_PORTC_BASE, GPIO_PIN_7, 0);
2- Where the link command file is configured? I saw that the linker takes the cmd file in the cmd folder but I didn't find where the project configures that.
3- I', trying to write in the shared ram to comunicate between cores whitout using the IPC commands. I did that:
RAMMReqSharedMemAccess(S7_ACCESS,SX_M3MASTER);
// Send C28 messages
unsigned long *pulMsgRam; // Vector to send messages to C28
pulMsgRam = (void *)S7_ADDR; // Points to S7 SRAM
pulMsgRam[0] = 1234;//(unsigned long)i_plus1;
// Receive C28 messages
unsigned long *getMsgRam; // Vector to write message to M3
getMsgRam = (void *)S7_ADDR; // Point to S7 SRAM
get1 = getMsgRam[1];
RAMMReqSharedMemAccess(S7_ACCESS,SX_C28MASTER);
I cant see at each side that I can write but I can't see at the other core the value wrote by other core.
