Part Number: F28M35H52C
Other Parts Discussed in Thread: C2000-GANG,

Dear team,

My customer is using F28M35H52C and C200-GANG. The Memory Option in the C2000-GANG software supports only 0x681000 - 0x68101F for the 28M35H52C OTP programming address range.

But i checked the datasheet and users guide,It showed that the start address of OTP is 0x680800.

In C:\ti\controlSUITE\device_support\f28m35x\v207\MWare\cmd, it also showed like the following

    OTPSECLOCK       : origin = 0x00680800, length = 0x0004
    OTP_Reserved1    : origin = 0x00680804, length = 0x0004
    OTP_Reserved2    : origin = 0x00680808, length = 0x0004
    OTP_Z2_FLASH_START_ADDR             : origin = 0x0068080C, length = 0x0004
    OTP_EMACID       : origin = 0x00680810, length = 0x0008
    OTP_Reserved3    : origin = 0x00680818, length = 0x0004
    CUSTOMER_OTP_MAIN_OSC_CLK_FREQ      : origin = 0x0068081C, length = 0x0004
    OTP_Reserved4    : origin = 0x00680820, length = 0x0004
    OTP_BOOT_MODE_GPIO_CONFIGURE        : origin = 0x00680824, length = 0x0004
    OTP_Reserved5    : origin = 0x00680828, length = 0x0004
    OTP_ENTRY_POINT  : origin = 0x0068082C, length = 0x0004
    OTP_Reserved6    : origin = 0x00680830, length = 0x0010

Please help.

Susan,

Datasheet and the linker cmd file are correct.

Not sure if there is a recent change in the C2000-GANG that introduced this bug.

I will ask Elprotronic to check this for you.

You can contact them at support@elprotronic.com.

Thanks and regards,
Vamsi

Susan,

Since I did not receive any feedback from you, I assume you are able to use the package fine.

I have been on vacation since September 28th, so I was unable to respond to you in time. After using the beta version, I found that the following problems still exist.

1 Now the OTP programming address range in the Memory Option can indeed contain 0x680800, but after clicking the Open code file in the software and selecting the file with this address, it will still report that 0x680800-0x680804 is out of range.

2 The 28M35 M3 core has a program burning problem. If you burn a code file without a CSM password, you can burn it all the time. If you burn a code file with a CSM password, you can only burn it once in the first time without a password, and then you won't be able to burn it.
