[C++知识库]NXP KL03--6.KL03 ISP 升级机制

1.bootload的参考手册最高支持57600。你试一下。

在这里插入图片描述

					//when mcu no bin ,ov FF FE 01 01 06 07  ---MCU30 CE FE 30 00 00 0E 00 06 60 0E 00 C0 00 0E 0E F0 CE

5A A7 00 00 01 50 00 00 29 AE is Generic Response

3.串口发送命令截图
在这里插入图片描述

4.OV788 UART 9600bps 升级KL03 OK

6.crc 计算
xxx@linux:~/data/ovipc/mcucrc$ cat crc.c

#include <stdio.h>
//typedef uint32_t unsigned int;
typedef unsigned int uint32_t;
typedef unsigned short uint16_t;
typedef unsigned char uint8_t;
//typedef uint16_t unsigned short;
//typedef uint8_t unsigned short;
uint16_t crc16_update(const uint8_t * src, uint32_t lengthInBytes)
{
uint32_t crc = 0;
uint32_t j;
for (j=0; j < lengthInBytes; ++j)
{
uint32_t i;
uint32_t byte = src[j];
crc ^= byte << 8;
for (i = 0; i < 8; ++i)
{
uint32_t temp = crc << 1;
if (crc & 0x8000)
{
temp ^= 0x1021;
}
crc = temp;
}
}
return crc;
}
