BSL Access under v5
I upgrade CCS to v5 and tried load a modified version of the BSL into a MSP430 but I am receiving “MSP430: Trouble Writing Memory Block at 0x1010 on Page 0 of Length 0x4: Could not perform access, BSL memory segments are protected”
The BSL worked fine under v4 and I’ve tried a different chip just to make sure the fuse wasn’t set. I was able to dig through the settings to find the “Allow Read/Write/Erase access to BSL memory” but that still does not work. Are there any other new options in v5 that need to be changed to allow this?
Not sure why this got moved from CCS forum as this doesn't seem to be a chip issue (I could program the chips just fine with CCS v4).
I've verified that the NRST and TEST pins are being triggered correctly and even tried a fresh out of the package chip.
Has anyone else had success with CCSv5 programming the BSL?
Indeed, it looks like the "unprotect BSL area" settings are no longer working. Then the error message is of course correct :)If it works with CCS V4 on the same chip, then it definitely isn't an MSP hardware problem.

But please do so only if you really cannot do it in a public thread, as I usually read all threads. And I prefer to answer where others can profit from it (or contribute to it) too.
Check your dll version (right-click, properties,details). Probably you upgraded your emulator's firmware as recommended by your IDE. I had the same problem when I used the latest Elprotronic's Lite Fet-Pro430, that uses a MSP430v3 dll.
I'm not sure, but it seems that the new MSP430v3 is bugged in respect to writing to BSL.
You can try to downgrade your emulator to a MSP430v2 using TI tools from MSP430 developer package and use an old msp430.dll, as I did.
I feel that down grading to the previous version is a good work around, but I'm hoping someone at TI actually sees this and comes out with a fix.
Is there anywhere to post bugs besides the forums?
Not that I'm aware of - the bug tracker has only a guest access so you can see what happened to your bug (if someone provided you a tracker ID).
Maybe you can contact Markus - or leave a message in the announcement thread of the MSP430.DLLv3 - it could be that Markus has a subscription to that thread and reacts faster that way.
So that adds another issue to the v3 - the other I know of is more of an inconvenience (clock cycle counter not working), but this one is a serious flaw. If TI was aware of this, I think it was a rather fast move to release and basically enforce the use of v3 with CCSv5.1 and other third party tools as well.
Maybe Katie will also look into this - she's also replying quite often to problem concerning the different MSP430.DLLs.

open project properties. Debug->MSP430 Properties, select "Erase main, information and protected information memory" and "Allow Read/Write/Erase access to BSL memory"
Thanks Daniel for reminding me that I haven't closed on this issue. Those were the settings I had tried, and had worked in v4. Since opening this thread I had received a CCS update from TI that fixed other issues (particularly sprintf bugs). I hadn't tried the BSL programming until today and it now seems to work.
