Part Number: TMS320F28375S
All:
Two points from the referenced e2e post - can someone confirm that this is also the case with the F2837xS?
1) DSP Unlocking
To lock the device, you can use DSP2833x_CSMPasswords.asm to program your passwords and secure your device. The passwords are linked to a section which is mapped to the appropriate memory addresses by the linker command file. In order to unlock your device, see Figure 12. You need to read 0x33FFF8-0x33FFFF. After performing these dummy reads, you need to write the correct passwords to 0x0AE0 - 0x0AE7. If the passwords match, the device will unlock.
2) Secured DSP Debugging
You cannot debug secure memory. You cannot connect CCS through JTAG to the device while it running from secure memory. The text that you posted means that code running from secure memory can read write and execute to secure memory. However, you cannot access the code via JTAG. you cannot read or write from unsecure memory including a JTAG connection.
If you connect via the JTAG emulator to the device and reset the device and it boots to secure Flash, then the emulator will get disconnected. Wait in Reset, allows you to connect to the device before it jumps to your secure application. You can do some debugging this way. You cannot debug secure memory while your device is secure. This would defeat the purpose of securing your device.
