Hello,

Please kindly check if your MCU has CAN bootloader inside first.

You can refer to following KBA for information about 16LX serial writing or programming:

F2MC-16LX Flash serial writing

"

Program with FLASH serial via CAN

To program with serial writer (e.g. YDC products) via CAN to FLASH MCU is supported.
At first of all, boot program (possible to get from YDC) is needed to be programmed already to FLASH MCU, but it can be programmed to FLASH MCU via CAN by it.

Best regards,

Amy

As  a matter of fact, I am not sure that if the bootloader inside the MCU. I do not have source files, I just got firmware file. It begins at 70000H, see attach.

I also upload the firmware file for you , would you please check it for me?  thanks!

我们的MCU出厂是没有带CAN Bootloader,通常都是客户自己开发或者第三方开发的。所以抱歉我无法提供帮助。请联系开发你们使用的CAN bootloader相关人员。

你好,你的意思是Bootloader是相当于私人定制的对吧,那我想知道 厂家这边,对Bootloader的开发有没有什么规范和定义,另外有没有参考例程和说明,谢谢。

另外,我在这里UBS (CAN)  for 16FX Family,找到了一个文件叫canproflash.pdf,然后最后边,提到了一张CD,我想知道我哪里可以购买或得到,谢谢。

关于MB90F497 Bootloader参考例程,请参考下面链接里的UART bootloader.

https://www.cypress.com/documentation/software-and-drivers/90495-bootloader-uart1-async-v14

你提到的CD相关的信息,请联系Cypress的销售或者分销商。

另外请注意我们现在已经不推荐使用老的16LX MCU设计新的应用了。
