在env工具中打开SPI驱动调用函数报错怎么解决

在env工具中打开SPI驱动,然后在RA Smart Config 中设置好SPI0之后,在hal_entry.c中加入以下代码

void spi_test(void *parameter)
{
struct rt_spi_device *my_spi;
struct rt_spi_configuration cfg;
int cs=10;
rt_uint8_t mssg = 0xf1;
rt_uint8_t w25x_read_id = 0xf1;
rt_uint8_t id[5] = {0};
my_spi = (struct rt_spi_device *)malloc(sizeof(struct rt_spi_device));
rt_spi_bus_attach_device(my_spi,"spi01","spi0",&cs);
my_spi = (struct rt_spi_device *)rt_device_find("spi01");
cfg.data_width = 8;
cfg.mode = RT_SPI_MASTER | RT_SPI_MODE_0 | RT_SPI_MSB|RT_SPI_NO_CS;
cfg.max_hz = 20 * 1000 *1000;
rt_kprintf("1\r\n");
rt_spi_configure(my_spi,&cfg);
rt_kprintf("2\r\n");
my_spi->bus->owner = my_spi;
struct rt_spi_message msg1,msg2;
msg1.send_buf = &w25x_read_id;
msg1.recv_buf = RT_NULL;
msg1.length = 1;
msg1.cs_take = 1;
msg1.cs_release = 0;
msg1.next = &msg2;
msg2.send_buf = RT_NULL;
msg2.recv_buf = id;
msg2.length = 5;
msg2.cs_take = 0;
msg2.cs_release = 1;
msg2.next = RT_NULL;
rt_thread_mdelay(500);
rt_kprintf("3\r\n");
rt_spi_transfer_message(my_spi,&msg1);
//rt_spi_transfer(my_spi,&mssg,RT_NULL,sizeof(mssg));
//rt_spi_send(my_spi,&mssg,8);
rt_kprintf("4\r\n");
}
MSH_CMD_EXPORT(spi_test,spi_test);

编译后下到板子里,hal_entry()中调用此函数,报如下错误

此代码我在STM32中测试过,是可以正常使用的.

之后通过打log,发现问题出在了

rt_spi_transfer_message(my_spi,&msg1);

不知道怎么解决这个问题,或者是我哪里写的有问题.
