CC1350: Programming through UART

Hello ,

I have tried this ,now i am attaching screenshot of my connection please check it. because still i am facing above issues.

Thank You

Nilesh

Try to refer to sunmaysky.blogspot.com/.../how-to-use-serial-bootloader-mode-to.html

hello sir,

I do the connection as per the link you have provided. it works. but i don.t want to use the another 4 pins i.e TMS,TCK,TDO,TDI except uart pins DIO2 and DIO3.

for programming through UART when i have removed this pins connector from my CC1350 LP. then it doesn't work.showing some error while flashing the binary.

Thank You

Nilesh Dalvi

You should select XDS110 Class Application/User UART instead of Prolific USB-to-Serial according to your picture. By the way, make sure you do mass erase to your CC1350 before you want to test serial bootloader FW update.

Can i remove the another 4 pins from the LP for UART programming

Which 4 pins do you mean here?

@Alex, DIO0 and DIO1 as serial bootloader TX/RX pins are only valid for 5x5 package. For 7x7, they are DIO2 and DIO3. For 4x4, they are DIO1 and DIO2. For details, you can refer to http://www.ti.com/lit/an/swra466b/swra466b.pdf

Hello Sir,

4 Pins means TMS,TCK,TDO,TDI , and if remove this connector from the CC1350 LP  will it program through only DIO2 and DIO3 pins through UART. because i am done this but i get the error.

When you use serial bootloader, you don’t need those four pins, TMS,TCK,TDO, and TDI.

Hello Sir,

here i am attaching screenshot of my connection for the uart programming. now i am using XDS110 user UART application. but still the window is showing the error while programming through UART.

i have change the boot loader configuration in ccfg.c file also i remove the 4 pins from the LP

please suggest me the sequential execution flow for the UART programming. i am new on TI, so i am not that much of hand on it.

please provide me sequence with connection now i am using the CC1350 LP.

Thanks 

Nilesh 

See figure 1 in 

If you are not using a bootloader backdoor, is your flash empty?

If you do mass erase before you use serial bootloader to download FW, does it work?

No , after connection , i have select the device and try connect it but it failed

Do  you do mass erase before you use serial bootloader?

No, but for the mass erase the device should be connected right?

hello ,

Is this below setting right for the above connection

#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 0x07 // 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

I couldn’t understand your question “for the mass erase the device should be connected right?”

Your setup looks correct, but in the picture of the launchpad that is supposed to show your setup, I can't see that you have set DIO7 high?

in configuration i have set like below

#define SET_CCFG_BL_CONFIG_BL_LEVEL 0x1 // Active high to open boot loader backdoor

it's active high so it is right?

It depends on what you actually sets this pin to... Have you tied DIO7 to VDD when you try to connect to the bootloader? 

No,Actually DIO7 is connected to green LED of the LP. as per the Schematic.

I think you should try to follow TER’s suggestion to connect DIO7 to VDD to see if it works.

Please i  am attaching connection setup with RS232 connector. Error Picture .

please see this and suggest any thing remains in the setup. 

According to your CCFG settings, you should try to connect to VDD to test again.

what is means according to your CCFG settings, you should try to connect to VDD to test again.

now in set up i  connect the DIO7 pin to VDD

I think you should remove jumper on green LED.

Hello,

I remove the jumper from the green LED. still the showing same error.

Thanks 

Nilesh

Run out of idea why it doesn't work in your case.

Hello Sir,

As per your suggestion i did each and every changes ,i share you the connection and bootloader setting in my CCFG. file. Failed error pictures.

i am also out of understanding why this is not work.

Again i am telling you flow.

1. Change the ccfg.c config file as per above picture.

2. compile the source code

3. after i open the flash programmer 2 software.

4. browse the .out file from the local directory

5.connect the board as per above connection. 

6. then connect it.

that's all about the connection setup

Does it work if use the XDS110 as UART (just connect power and RxD, TxD on P4 on the launchpad)? 

I see that you have connected to the 5V on the launchpad, note that this is not connected to anything, I assume that you don't use 5V to anything. 

Hello sir,

It is not work If if use the XDS110 as UART (just connect power and RxD, TxD on P4 on the launchpad) as per configuration file change.

Now what i did, change the ccfg.c file  as below

#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 0x07 // 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

there  is LED blinking code which blink the led only. By using above configuration i program the LP board through CCS studio software.

1) after programming board LED start blinking but when i remove the USB cable and again connected to PC. LED stop Blinking. this is first case

2) Same board programmed with backdoor enable, programmed successfully through USB to serial converter on Flash Programmer 2 software as per above screenshot with same Led blinking source code .out file. but  it programmed successfully but LED not blinked as per source code.

This are the issue comes when i enable the boot loader in ccfg.c file. please suggest about this issue.   

Nilesh,

Are you able to reproduce this issue on another Launchpad?

BR,

Seong

Same issue happen on another board also. means when i enable the backdoor in config.h file then programmed board it start blinking at first time when USB connected to PC ,once i removed USB cable and connect it again the device not work.

Nilesh,

Happy New Year!

Please use a logic analyzer to probe the physical UART signals and share the capture with us. 

Thanks,

Seong
