TMS570LS1224: CAN Bootloader

Zeynep Arslan

Part Number: TMS570LS1224
Other Parts Discussed in Thread: TMS570LS0232, TMS570LS0432

Tool/software:

I am using tms570 bootloader via uart. I am trying to enable CAN interrupt. When I enable it it works on debug mode but if I load via jflash it wont work and when I send a can message bootloader stops. What could be the reason of it.

I enable it on CANMessageSetRx

node->IF1MCTL= CAN_IFMCTL_UMASK | CAN_IFMCTL_EOB | CAN_IFMCTL_RXIE;

Where

CAN_IFMCTL_UMASK = 0x00001000

CAN_IFMCTL_EOB = 0x00000080

CAN_IFMCTL_RXIE = 0x00000400

Hi Zeynep Arslan,

I am suspecting one reason for not working interrupts:

Thank yu for your reply I made a mistake when I said I am using TMS570ls1224. I am using tms570ls0232 and it has all the init that you say in systemstartup.c.

/* USER CODE BEGIN (26) */
/* USER CODE END */
/* Initialize System - Clock, Flash settings with Efuse self check */
systemInit();

/* USER CODE BEGIN (29) */
/* USER CODE END */

/* USER CODE BEGIN (31) */
/* USER CODE END */

/* USER CODE BEGIN (37) */
/* USER CODE END */

/* USER CODE BEGIN (55) */
/* USER CODE END */

/* USER CODE BEGIN (68) */
/* USER CODE END */

/* USER CODE BEGIN (72) */
/* USER CODE END */

/* Enable IRQ offset via Vic controller */
_coreEnableIrqVicOffset_();

/* USER CODE BEGIN (73) */
/* USER CODE END */

/* Initialize VIM table */
vimInit();

Hi Jagadish,

Unfortunately it is not possible for me to share the code. But I use UART bootloader for hercules. I don't undertand that when I use it in debug mode CAN interrupt works but when I load the bootlader it dosn't work. If it wasn't clear I dont load app now. I am just changing bootloader. Just trying to add to bootlader an interrupt.

Thanks & Regards,
Zeynep

Hi Zeynep,

We have one tested CAN bootloader example on TMS570LS0432. I am attaching the corresponding project for your reference.

Can you please verify it, this is similar to the TMS570LS0232 you are using.
