使用MCC配置bootloader
本帖最后由 TsaiRH 于 2020-4-16 19:43 编辑就一个多月学习bootloader做个记录，同时对lcczg的解答表示感谢。文中的很多内容摘抄于Microchip 2017 Master的课程《C18H04 21041_BTL1 Lab Manual_cn 1719.pdf》和21ic上lcczg的《给PIC16F18446 curiosity nano板做个bootloader》（https://bbs.21ic.com/forum.php?mod=viewthread&tid=2823060&page=1#pid10883760）教程。准备：MPLAB X IDE V5.20XC8 V2.00PIC16F18446 curiosity nano 开发板USB串口调试工具实验1“新建编译应用程序”1、启动MPLAB X，新建一个项目，编写应用程序，编译下载到板上，验证功能，我这直接使用lcczg提供的led_app.X，功能为led闪烁。实验2“生成UART自举程序”1、创建新项目。器件：PIC16F18446编译器工具：XC8 V2.00项目名称：“BTL_V2.0”2、启动MCC。3、在System Module（系统模块）窗口中，选择以下振荡器：INTOSC oscillator:I/O function on CLKIN pin。Internal Clock选择位16MHz_HF。
4、在Device Resources（器件资源）窗口中，选择EUSART1、MEMORY和Bootloader Generator。5、EUSART1，使能发送和连续接收。代码将使用自动波特率，因此我们不必在此设置。 6、MEMORY，不需要配置。7、Bootloader Generator（1）、Transport Type：UARTEUSART（2）、Verification：Check_State_Flag。（3）、Application Reset Vector：0x300，（4）、Enable IO Pin Indicator and Software Protection.
8、Pin Manager Grid （引脚管理器网格）RB7设置TX1，RB5设置RX1，RA2 设置BL_INDICATOR(BOOTLOADER指示灯)，Disable所有选中引脚模拟功能。
9、Generate（生成）（忽略警告）。10、选择project（项目）选项卡,右键单击项目以启动Project Properties（项目属性）窗口。 11、单击XC8 Linker（XC8链接器），选择Memory Model（存储器模型）下拉选项卡，如下配置，这将使自举程序位于存储器的前0x300字中。12、编译项目编译失败，错误提示不能找到空间，对空间加点优化。Non line specific message::: advisory: (1493) updated 32-bit floating-point routines might trigger "can't find space" messages appearing after updating to this release; consider using the smaller 24-bit floating-point types
编译成功。13、使用板载nEDBG下载。先做个修改：#defineBL_INDICATOR_ON 0#defineBL_INDICATOR_OFF1因为板子文档里的说明是接到地（RA2=0）亮，反掉了。下载到板上，这是LED常亮。
实验3“将自举程序连接到应用程序”1、创建偏移应用程序（1）、重新打开led_app.X，创建偏移应用程序。（2）、转到Project Properties窗口。（3）、选择XC8 Linker，然后选择Additional options（其他选项）选项卡。（4）、将项目偏移设置为0x300。单击Apply。（5）、编译项目。2、自举偏移应用程序（1）、用串口调试工具连接好Nano板上的TX、RX，将串口调试工具插到PC的USB口中。（2）、在官网https://www.microchip.com/promo/8-bit-bootloader最下面右侧下载Bootloader HOST，我们将通过它下载应用程序。（3）、启动统一自举程序java应用程序。
（4）、在Settings（设置）菜单中，选择Serial（串行），然后正确的UART。
（5）、将端口配置为19200，8个数据位，1个停止，禁止奇偶校验。单击“Apply”关闭窗口。（6）、自举程序主机按字节地址和长度工作，因此我们必须通过将PIC16字地址乘以2进行转换。将程序存储器大小设置为0x8000，将自举程序偏移设置为0x600。
（7）、选择File Open/Load（文件打开/加载）下拉菜单，打开应用程序的Hex文件。 （8）、点击“Program Device”（编程器件）按钮。最终器件得到与实验1相同的LED等闪烁共能。实验视频：https://v.youku.com/v_show/id_XNDYzNTA3NjY3Ng==.html

现在又遇到一个问题，使能I/O Pin Entry，编译不通过
更新，注释掉这行代码——#info"You may need to add additional delay here between enabling weak pullups and testing the pin."编译成功，实现功能：上电是，按住按键，进入boot loader 学习了！ 不错的东东，可以看看！ 我按照步骤对 PIC18F26K22 用MCC产生bootloader 成功，程序运行正常，但是 EEPROM编程失败。请教是什么原因造成的呢？附件为我的配置。EEPROM的OFFSET 已更改是多少？0x00不对，默认也不对。不知道什么问题。Flash烧录正常，程序运行正常。就是eeprom的数据不能写入。 asm ("psectintcode,global,reloc=2,class=CODE,delta=1");
asm ("GOTO " str(NEW_INTERRUPT_VECTOR_HIGH));
asm ("psectintcodelo,global,reloc=2,class=CODE,delta=1");
asm ("GOTO " str(NEW_INTERRUPT_VECTOR_LOW));
请教一下，这4句有什么作用？ 本帖最后由 klz198327 于 2021-6-16 08:11 编辑
学习了，这里的 ROM rangse 储存器0-2ff是什么意思呢，是指什么储存器，EEPROM还是程序储存器

做bootloader跟EEPROM似乎是没有关系的...
你这里"EEPROM编程失败"是要对EEPROM做了些什么操作??? 我也出现了下面这个问题，加了优化也不管用啊！
我使用的是PIC18F55Q43，8bit MCU，UART5 - RF0（RX）- RF1（TX），复位向量定位到了0x500.使用了BL_INDICATOR ,BL_ENTRY.bootloader library版本2.4.1。 能帮我在您电脑上生成编译下试试吗？哪位朋友看到也请帮顺手试下吧，是我安装软件的问题吗？

提示和浮点数操作有关，这是建议，没错呀。把你的工程传上来。 MCC里的bootloader要被各位发扬光大了 芯片是PIC18F55Q43。使用的bootloader库是2.4.1， PIC库文件是1.81.7。IDE是 MPLAB 5.50， 编译器是XC8 v2.32.
使用外设有UART5， 波特率115200，异步8bit，使能接收发送。
memory，默认
UART5RX --- RF0
UART5TX --- RF1
bootloader使用了 i/O INDICATOR, I/O ENTRY， 和I/O protect。application reset vector 为0x500
BL_INDICATOR --- RA0
BL_ENTRY ----RA5。
生成代码后，选择了优化等级 s,代码空间0 - 4FF。 编译就提示上面问题“Non line specific message::: advisory: (1493) updated 32-bit floating-point routines might trigger "can't find space" messages appearing after updating to this release; consider using the smaller 24-bit floating-point types”

做了一点修改 1. ROM range 为0-7FF，少了就空间不够。2. 配置字 #pragma config BBSIZE = BBSIZE_1024
这是和ROM做了对应，另外Boot block Enable #pragma config BBEN = ON 这个很方便啊 lcczg 发表于 2021-8-3 11:15
