Good moorning,
I am trying to use LwIP to do a RAW Socket TCP connection. I have did it without problems but i used the compiler 5, i want add this development to another proyect that i am doing but in that i use the compiler 6. When i try to migrate it, appears too many compile errors.
Do you know if there are any limitations? Someone use LwIP with the compiler 6?
I am working with a ST microcontoller, the STM32F779NI. The IDE that use is the KEIL MDK.
I hope you can help me. Thank you very much for you time.
Good Moorning,
I finaly resolved it.
First i found the correct sintaxys for DMA reserve.
// Ethernet Rx DMA Descriptors __attribute__((section(".ARM.__at_0x2007C000"))) \ ETH_DMADescTypeDef DMARxDscrTab[ETH_RXBUFNB]; // Ethernet Rx DMA Descriptors __attribute__((section(".ARM.__at_0x2007c080"))) \ ETH_DMADescTypeDef DMATxDscrTab[ETH_TXBUFNB]; // Ethernet Rx DMA Descriptors __attribute__((section(".ARM.__at_0x2007C100"))) \ uint8_t Rx_Buff[ETH_RXBUFNB][ETH_RX_BUF_SIZE]; // Ethernet Rx DMA Descriptors __attribute__((section(".ARM.__at_0x2007D8D0"))) \ uint8_t Tx_Buff[ETH_TXBUFNB][ETH_TX_BUF_SIZE];
Second i changed the memory map in sct file. I changed the size of IRAM1, for have a space reserved.
RW_IRAM1 ADDRESS SIZE{ ;RW data .ANY(+RW +ZI) } ; ************************************************************* ; *** Scatter-Loading Description File generated by uVision *** ; ************************************************************* LR_IROM1 0x08000000 0x00200000 { ; load region size_region ER_IROM1 0x08000000 0x00200000 { ; load address = execution address *.o (RESET, +First) *(InRoot$$Sections) .ANY (+RO) .ANY (+XO) } RW_IRAM1 0x20020000 0x0005C000 { ; RW data .ANY (+RW +ZI) } RW_IRAM2 0x20000000 0x00020000 { .ANY (+RW +ZI) } }
Thank you very much for you time and help.
