I'm using MSP430F248 and I 'm planning to use the BSL for upgrading the Flash.

The doubt I have is in choosing the UART communication protocol with the BSL. For MSP430F248, I want to know if I should use ROM based BSL protocol or FLASH based BSL protocol.

Thanks

To have doubt is better than to have faith. You misunderstood TI's terminology.

F248 has "ROM based BSL", no "Flash based BSL". You do not have a choice. But you could implement your own "BSL" in Flash and use whatever protocol you want, including your own invention. TI's BSL Entry Sequence cannot enter your own BSL through.

I tried the ROM based BSL protocol and was able to implement the RX password and mass erase commands.

But I'm struck with RX Data Block command. I tried to flash my actual application which has multiple packets. Although I get ACK for the first packet I get NAK-0xA0 for the second packet.

I also tried to flash the software with another application whose size is less than a packet. Now it failed even in the first attemp.

Could someone know help me know what the issue could be?

Thanks for the info.

This is the hex file I'm trying to flash:

Since I had error receiving NAK for second packet, I modified the line "@4102" by removing it and appending it. I don't know why @4102 is introduced in the file though the address is in sequence.

Before modification:
01
@4102
31 40 00 21 3C 40 02 11 3D 40 FC 02 B0 12 32 46

After modification
01 31 40 00 21 3C 40 02 11 3D 40 FC 02 B0 12 32 46

Now I was able to successfully RX Data block through BSL. After transfering the whole file I powered up the system. But, the microcontroller is not functioning.

Any thoughts?

Working!

With the option in linker to write 0xFF in the free spaces, I was able to successfully flash the code and the microcontroller seems to be working.

Now my question is,
I'm doing a mass erase before transferring the data so I believed it would clear of all the locations with 0xFF. If it is true, then how does this enabling of 0xFF makes the difference?

Thanks old_cow for your valuable inputs.

(You need to be a member of msp430 -- send a blank email to msp430-subscribe@yahoogroups.com )

I didn't look at your file/emails before in detail.

But my educated guess is that you were trying to write data block with odd =
number of bytes. (read the BSL spec crafully; L1=3DL2 and L1 must be even).=
Otherwise you'll get the NACK from the BSL.

So this time around, once the linker padded the empty spaces with 0xFFs, al=
l your possible data block sizes became even numbered.

Whatever (custom) program you are using to read the s-record or ti file mus=
t pad the data block if odd number bytes are present. (or filling with 0xFF=
s will work too).

=A0=20
Working!

With the option in linker to write 0xFF in the free spaces, I was able to s=
uccessfully flash the code and the microcontroller seems to be working.

Now my question is,
I'm doing a mass erase before transferring the data so I believed it would =
clear of all the locations with 0xFF. If it is true, then how does this ena=
bling of 0xFF makes the difference?

Thanks old_cow for your valuable inputs.

Which PC BSL program did you use?

As I said, I do not know why it did not work before you filled the unused bytes with FF.

I suspect that the programmer made a very common mistake of only thinking of the trivially simple cases, test that, and declares "it works perfectly". It seems that I was not wrong.

As Mentioned earlier, ROM Based BSL one as described in slau265.pdf.

Candemir,

Your guess was right. I looked into TI BSL_Scripter (Jan2009) by L.Westlund. It sure made the mistake you speculated.

Ironically, an earlier PC program called BSLDemo (May2000) by Volker Rzebak (also at TI) does work correctly in this respect. But, of course, BSLDemo is now "Deprecated" in slau265.zip

You probably are referring to a PC program called BSL_Script (circa 2009). In the "Deprecated" folder there is an older one called BSLDemo (circa 2000).

We are fortunate that progress has been slow, otherwise we would be in much deeper trouble -- because it was moving in the wrong direction. The old one works fine. The new one has the bug you just found.

OCY,

Good to know you were able to confirm. Too bad it's actually in TI's own demo code. The quality of code I'm seeing them is on the decline for sure. Perhaps it's because of the volume. (but that's not a good excuse)

BTW, it was more than speculation on my part: Recently, I developed a custom PC program to program/upgrade two MSP430s over a single USB link using the BSL. This was a single device I had developed firmware for, as well.

My PC program ended up having the same bug. After some simple debugging and a RTFM moment, all was good.

Candemir,

Your guess was right. I looked into TI BSL_Scripter (Jan2009) by L.Westlund. It sure made the mistake you speculated.

Ironically, an earlier PC program called BSLDemo (May2000) by Volker Rzebak (also at TI) does work correctly in this respect. But, of course, BSLDemo is now "Deprecated" in slau265.zip
