stm32h7 spi dma receive error

[gcaif]

I want to use w5500 on stm32h7 board. Using HAL_SPI_Transmit_DMA() can send msg sucess.But Using HAL_SPI_Receive_DMA() can receive data sucess one time,and run second time,the DMA status is busy tx,and the lock status is locked.

the picture is w5500 receive data timing

[Ayuks.1]

when debug, everything is good and working. but If I shut down the computer then I cannot connect to the processor again. When you enter the ethernet settings from the control panel and turn the ethernet off and on, it works normally again. how to solve this error. can you help me. my mcu is working tcp server mode. ı am using tcp comunication.

ı am using stm32f407vg .w5500 module .

my code

/* Open socket 0 as TCP_SOCKET with port 5000 /
