TMS570LS0914: Bootloader for TMS570LS0914

Hi QJ Wang,

While downloading the application bin file it is stuck in Fapi_BlockErase function 

while(FAPI_GET_FSM_STATUS != Fapi_Status_Success); condition, So I have traced the HCLK system clock configuration it is 240 

Please check and confirm me the setting for Sys_CLK_FREQ is correct or not.

Thanks in Advance

HI Santhosh,

The maximum CPU frequency for TMS570LS0714PZ is 100MHz. The 240MHz in your config is invalid.

Hi QJ Wang,

TMS570LS0914PZ configured as 80 and 100MHz both has the same issue.

After I have commented on this while(FAPI_GET_FSM_STATUS != Fapi_Status_Success); condition

it is stucked in previous while( FAPI_CHECK_FSM_READY_BUSY == Fapi_Status_FsmBusy );condition itself 

So I have tried to run the code reset and run

it jumps to undefentry in sys_intvecs.asm file

I have check both 100Mhz and 80 MHz frequency. 

Please check the link file and sys_intvecs.asm file

Please check and confirm as soon as possible 

Thanks in advance.

Hi Santhosh,

The SYS_CLK_FREQ should be system clock. If CPU clock is 80MHz, the SYS_CLK_FREQ = 80MHz.

Hi QJ Wang,

Yes it is same, but still It is not working. 

Is there any other issue.

RTI is configured in HalCoGen and bootloader code 

Where is the code for RTI in bootloader 

It is again stuck in Download Application image.

Thanks in advance.

Hi QJ Wang,

I have a doubt in the UART baudrate is fine for TMS570LS0914 MCU is 115200 or it is better to use 9600 ?

and one more doubt is about my application address is okay or not.

Please suggest me how to split the memory.

Please check and confirm as soon as possible.

Thanks in advance.

Hi QJ Wang,

Today,  I faced a issue after changed to 100MHz for HCLK and VCLK1

After press 1 for download application image 

  1. Download Application Image To the Internal Flash

After timeout from remote system it is gone to dabort.asm in bootloader.

Can you please guide me to debug this issue.

Thanks in advance.

Hi QJ Wang,

Please can you share the bootloader for TMS570LS0914 MCU specific  ?\

Thanks in advance.

Hi QJ Wang,

I have define the flash sectors for TMS570LS0914 MCU in  flash_defines.h file.

and the link.cmd file 

download the application image to internal flash has issue 

and stuck it here 

Please check and feedback as soon as possible 

Thanks in advance

HI Santhosh,

This is the link to download CAN bootloader example:

https://git.ti.com/cgit/hercules_examples/hercules_examples/tree/Bootloaders/SafetyMCU_Bootloaders

The CAN bootloader example for TMS570LS0714 can be used for TMS570LS0914. Those two devices are same except the internal memory size. The example codes were tested and work.

Hi QJ Wang,

I have used the same build to develop UART bootloader for TMS570LS0914 from TMS570LS0714 build. which you have referred in first reply itself. 

  I faced a issue after changed to 100MHz for HCLK and VCLK1

After press 1 for download application image 

  1. Download Application Image To the Internal Flash

After timeout from remote system it is gone to dabort.asm in bootloader.

Can you please guide me to debug this issue.

please check what will be the issue in flash_defines.h file.

and the link.cmd file 

download the application image to internal flash has issue 

and stuck it here 

Please check and feedback as soon as possible 

Thanks in advance
