CC1310: How to implement SerialBootLoader

Mario Castaldo

Part Number: CC1310

Hi,

I'm trying to implement the BootLoader via UART on my program.

I have read various documents on how to set up the CCFG within my project and I get this:

//#####################################
// Bootloader settings
//#####################################

#ifndef SET_CCFG_BL_CONFIG_BOOTLOADER_ENABLE
//#define SET_CCFG_BL_CONFIG_BOOTLOADER_ENABLE            0x00       // Disable ROM boot loader
#define SET_CCFG_BL_CONFIG_BOOTLOADER_ENABLE         0xC5       // Enable ROM boot loader
#endif

#ifndef SET_CCFG_BL_CONFIG_BL_LEVEL
#define SET_CCFG_BL_CONFIG_BL_LEVEL                  0x0        // Active low to open boot loader backdoor
//#define SET_CCFG_BL_CONFIG_BL_LEVEL                     0x1        // Active high to open boot loader backdoor
#endif

#ifndef SET_CCFG_BL_CONFIG_BL_PIN_NUMBER
#define SET_CCFG_BL_CONFIG_BL_PIN_NUMBER                0xFF       // DIO number for boot loader backdoor
//#define SET_CCFG_BL_CONFIG_BL_PIN_NUMBER                0x0B       // DIO number for boot loader backdoor
#endif

#ifndef SET_CCFG_BL_CONFIG_BL_ENABLE
#define SET_CCFG_BL_CONFIG_BL_ENABLE                 0xC5       // Enabled boot loader backdoor
//#define SET_CCFG_BL_CONFIG_BL_ENABLE                    0xFF       // Disabled boot loader backdoor
#endif

Now, I read a post on this blog: https://sunmaysky.blogspot.com/2018/10/how-to-use-serial-bootloader-mode-to.html

I have done all the steps and it works well. I see the problem if I want to program it again. By connecting the device again without XDS110, I cannot load the .hex file.

Is there a need for a flash mass erase first?

Please read figure 1 in to see how to re-program the device without mass erase.

So, as I understand, I need a Pin to not do the mass erase. Quite right?

Yes, you have to define a boot loader backdoor and a pin you want to use for this.

I have defined a pin. When I try to bootloader and put the jumper on, I still can't load the program on the flash. Did I miss something?

In the above you have not defined a pin number in BL_PIN_NUMBER?
