Problem with writing OPT Bootloader (with CAN)

Hi.

Could you can help please with OTP writing problems?

I create own OPT Bootloader with CAN interface. How I do. I used example from TI site with OTP for 2812 and update code for 28335 with addidtion of our company protocol, and a little updated *.lnk, because searching why it not work. Actualy it is like prposed by TI, but added additional perepherials in LNK. More of them, I tied are few *.lnk linker files... Last version it just united sections as one. (instead of separated by .stack and .bbc anf .text)

And created Release compiled solution just do "Rebuild All" and F11 (to download into Flash) also tried classical "connection->...." result was same, Error.

Problem reproduce as: I has been tried download my OTP program into DSP TMS320F28335 (CCS v5) , But CCSv5 inform me about strange error like:

C28xx: Flash Programmer: Error encountered when writing to Flash memory
C28xx: Error writing: Flash @ address 0x00380400 of length 0x000003F8
C28xx: GEL: File: D:\work\...bla_bla...\my_file.out: load failed.

I was tried are few different board with new DSP problem same.

I not sure that it problem of CCS, think some other but don't know what

More of then, I tried to find detailed instruction how to correct write into OTP - no results.

Also tried set BOOT_PINS in to Flash_Mode and OTP_Mode, no differences.
