msp430f5504 MSC code problem

Other Parts Discussed in Thread: MSP430F5504, MSP430F5510

I'm trying to build the M1_FileSystemEmulation example (that is a part of the MSP430USBDevelopersPackage_4_10_00 package) on the msp430f5504. But no matter what I do, I cannot fit my pcode into the available memory.

(Keep getting:

"../lnk_msp430f5504.cmd", line 142: error #10099-D: program will not fit into available memory. placement with alignment fails for section ".text" size 0x31ac . Available memory ranges:

FLASH size: 0x1f80 unused: 0x1d66 max hole: 0x1d66 )

Did anyone was able to compile this example? Are there any other mass storage examples for this MCU?

The MSP430F5504 only has 8KB of Flash. That's not enough for this example project with the USB API library.

I would suggest using a device with more memory or perhaps the 5529 Launch Pad.

Thanks,

what would be the less expensive MCU this code work on (maybe the 510)?

First, you should determine how much total memory (Flash and RAM) that this application requires. Pick one of the "big" parts, run the design, and then look at the linker map output file to get memory totals.

Second, use the product selector tool at http://www.ti.com/lsds/ti/microcontroller/16-bit_msp430/overview.page to find a suitable MSP. Make sure to check "USB", adjust the sliders for min/max memory, and then sort on the price column.

Don't know about size related to MSC part, but base (TI USB stack) is oversized. You can try to remove not needed / not used parts and shrink size. My USB stack size is only 1 KB.

I tested all examples from TI USB stack (2 years ago) with MSP430F5510, and they worked just fine.

thanks,

would you mind sharing your code with me?

Unfortunately it is not open source and it is coded in assembler.

You can check open source version from JP Norair...
