Part Number: TMS320F28386S
Other Parts Discussed in Thread: SYSCONFIG, C2000WARE,

Hi All,

I have a question about rewriting pragram FLASH via USB.

① I have set the Boot PIN setting for the TI C2000 F2836x USB BOOT as shown in the image, is this OK?

② When I build after configuring with Sysconfig, I get the following error.
Is there any way to resolve this?

C28xx_CPU1: Error during Flash Programming. Address 0x00078008, FMSTAT (STATCMD on some devices) 0x00000030

C28xx_CPU1: File Loader: Memory write failed: Unknown error

③ I saw how to use a USB bootloader from a user program.
Is this possible with the F2838x?

Hi Ito,

Did you try the existing example provided within C2000Ware and the usb flash programmer utility?

Pls let us know if this works fine.

The utility can be used for F2838x also, however the Flash kernel code has to be written for it.

You can refer the existing example for F2837x and port it for F2838x.

Hi Siddharth,

A customer is asking about how to migrate.
The F2837x and F2838x APIs are similar, so I don't think there are any changes in registers, etc.
Would it be enough to change the header files?
If you have any specific porting instructions, please let me know.

Best Regards,

Ito

Ito,

The USB peripheral is same on these devices. While porting the following things needs to be considered

1. The clock frequency,

2. USB pins (pinmux will be different on these devices)

3. Interrupts
