Erasing DSP flash - Nimmy - Jan 25 7:50:24 2011
Hi all,
I have bought a few DSP - TMS320F2810 from a broker. When opening the
flash utility, the flash is password locked. When the password addresses in
flash memory((0x3F7FF8 - 0x3F7FFF)) verified, it shows all zeros. This
means that, the DSPs are already locked. But without knowing the password,
it can never be unlocked, using JTAG emulator.
Does , anybody know , some other method to erase the flash (including the
password )completely, so that I can reuse the DSPs.
Regards,
Nimmy Ranjit

Re: Erasing DSP flash - shei...@cranessoftware.com - Sep 29 9:59:15 2011
Hi,
The Flash memeory in C28x's are code protected. You need to unlock the flash memory if you want to erase/ to program. It is 128 bit password. The default password is all '1' ie "0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF".
try this.
regards
sheik
