Bluetopia + EABI

Other Parts Discussed in Thread: MSPMATHLIB, MSP430F5438A

Hi, my name is Luis Chaidez, I’m a firmware engineer from an electronic design center at the ITESM University in Guadalajara, Jalisco, Mexico.

We are using the MSP-EXP430F5438 development kit for developing a project, this kit has an MSP430F5438A Rev D MCU. The project involves using Bluetooth communication and some floating point algorithms. For Bluetooth communication we are using TiWi-uB2 module together with stonestreet one’s bluetopia stack (which uses “libBluetopia.a” pre compiled library). For floating point operations we want to use MSP math library (which uses “MSPMATHLIB_CCS_msp430_xxx_xxx.lib” pre compiled library). The problem here is that “libBluetopia.a” requires the application binary interface to be set to COFFABI and the math library requires the application binary interface to be set to EABI, so I can’t use both libraries at the same time.

The questions are:

Does TI provides MSP Math libraries compatible with COFFABI?

Or, even better, is there a chance to get bluetopia library precompiled with EABI?

Best regards.

Hi Luis,

We don't have a precompiled Bluetopia Library with EABI.

If you have a custom request, please contact sales@stonestreetone.com

Thanks,

Thanks Miguel, I'll wait for you'r response.

Miguel, I have one more question, I hope you can help me.. Is there a way in Code Composer to activate the automatic use of the hardware multiplier? (Like in IAR)

Regards.

Luis,

There is a way to do such configuration but I don't remember on top of my head. Do you mind looking/asking on the forum below please? You should be able to find the answer there.

Hello Luis,

We will support EABI format. But I don't have a timeline yet. It should be coming within the next 2-3 months. When do you need it for?

Regards,

Miguel

Hi Miguel,

We need it asap, our project first phase ends this month. Rigth now we are using normal math.h library in order to use coffabi with bluetopia library, but this math library si slow compared with mspmath library.

From your last answer I understand that bluetopia library will support EABI within 3 months, but, Is there a way to obtain mspmath library with COFFABI in about a week?

Regards.

Hello Miguel,

we too are in a position of needing Bluetopia libray in EABI format as we need NOINIT & PERSISTENT PRAGMAS...they aren't supported with COFF

Is this available?

Hi,

The new MSP430 CC256x SDK release should have EABI support. Did you look at it?
