MSP430F5504: Unable to develop CDC simple send code

TURJASU PYNE1

Part Number: MSP430F5504
Other Parts Discussed in Thread: MSP430WARE

Hi,

I have been trying to make a project now with MSP430F5504 where I will have to send just a few bytes of data to the PC and receive only may be few tens of bytes from PC. But after trying to integrate the C0_SimpleSend example provided by usblib here --> "C:\ti\msp430ware_3_80_11_07\usblib430\MSP430_USB_Software\MSP430_USB_API\examples\CDC_virtualCOMport\C0_SimpleSend" I encountered with the following error of "insufficient memory" :

../lnk_msp430f5504.cmd", line 144: error #10099-D: program will not fit into available memory, or the section contains a call site that requires a trampoline that can't be generated for this section. placement with alignment fails for section ".text" size 0x2aac. Available memory ranges:
FLASH size: 0x1f80 unused: 0x1f80 max hole: 0x1f80

I understand many have received the same issue and might have solved. But the thread links provided some are working and some no longer exists. Please help me regarding this issue.

Hi TURJASU,

The F5504 only have 8KB flash, I think maybe the device(F5504)do not have enough memory for the USB code.

Maybe you can test this USB code in F5529(128KB).

Thanks!

Best Regards

Johnson

Hi Johnson,

Thanks for your reply. I understand that the F5504 has 8 KB flash, but then it does have a USB peripheral. How can I use it then ? It would be nice if you could provide some links to make it work in this silicon.

I would not be able to use F5529. Instead I may opt for F5510 because the PCBs have been made for LQFP48 and also the costing of F5529 is higher. Will that be fine ?

Please help

TI USB stack is not lite. It can be optimized, and I remember right, jpnorair @ 43oh shrinked down original TI code significanly, but I don't have time now to search for it.

For example my USB stack written from zero in assembler together with BSL and AES fit in 2 Kbytes.

Hi zrno,

Thanks for your reply. Even I heard that in the forum posts and I even went though the net. But I was unable to find anything of that kind. It would be very helpful if I could get some document or atleast a starting point for that. I am very new to USB and hence need some help.

Hi TURJASU,

Those information maybe useful for you :

MSP430 MCUs include an on-chip USB 2.0 module on several subfamilies. Combined with the MSP430 USB Developers Package, the USB development will be simple.

GUI product page: MSP430 USB Developers Package
User’s guide★: Starting a USB Design Using MSP430 MCUs
Application notes:

And you also can refer this User guide:

Thanks!

Hi zrno,

Thanks a lot for the links! I have already done some tweaks with the TI's code and implemented on 5510 but these links will be very helpful for me to implement in 5504 flavor. Thanks again :-)
