新添加SPI的flash无法正常工作(BY25D16)
@armink 请帮忙看下这是什么问题呢.
<00> info> app: Start initialize Serial Flash Universal Driver(SFUD) V1.1.0.
<00> info> app: You can get the latest version on https://github.com/armink/SFUD .
<00> info> app: The flash device manufacturer ID is 0x00, memory type ID is 0x00, capacity ID is 0xBD.

在SFUD_FLASH_CHIP_TABLE的末尾已经添加了{"BY25D16", SFUD_MF_ID_BOYA, 0x40, 0x15, 2L1024L1024L, SFUD_WM_PAGE_256B, 4096, 0x20},
感谢
您好,感谢您. 1、在sfud_cfg.h里面定义了宏SFUD_USING_FLASH_INFO_TABLE，整个文件内容如下: `#ifndef SFUD_CFG_H #define SFUD_CFG_H
#define SFUD_DEBUG_MODE
#define SFUD_USING_SFDP
#define SFUD_USING_FLASH_INFO_TABLE
enum { SFUD_W25_DEVICE_INDEX = 0, };
//BY25D16 not support QSPI
#define SFUD_FLASH_DEVICE_TABLE
{
[SFUD_W25_DEVICE_INDEX] = {.name = "BY25D16", .spi.name = "SPI2"},
}
//#define SFUD_USING_QSPI
#endif /* SFUD_CFG_H */`
2、在sfud_port.c里面实现了spi_write_read函数，且通过之前的工程验证该函数读取写入flash是实现成功了的。文件代码如下： ` #include <sfud.h> #include <stdarg.h>
#include "nrf_drv_spi.h" #include "my_spi.h" #include "flash_driver.h"
#include "nrf_log.h" #include "nrf_delay.h"

void sfud_log_debug(const char *file, const long line, const char *format, ...);
static void spi_lock(const sfud_spi *spi) { //__disable_irq(); }
static void spi_unlock(const sfud_spi *spi) { //__enable_irq(); }
extern sfud_err spi_write_read(const sfud_spi *spi, const uint8_t write_buf, size_t write_size, uint8_t read_buf, size_t read_size); /

//FLASH_CS_LOW();
for (size_t i = 0, retry_times; i < write_size + read_size; i++) {
if (i < write_size) {
send_data = *write_buf++;
} else {
send_data = SFUD_DUMMY_DATA;
}
retry_times = 1000;
spi2_xfer_done = false;
while(spi2_xfer_done == false){
SFUD_RETRY_PROCESS(NULL, retry_times, result);

if (result != SFUD_SUCCESS) {

}

}

1、sfud_spi_port_init接口中发现需要release powerdown(0xAB)后方可正常使用SFUD，不知其他flash是否存在这个问题。 2、spi_write_read接口中CS拉低后需要延迟10ms，这个可能是和PCB板走线有关系。
