Hello all, I have been working on getting the ti-dsplink_1.64.bb recipe's kernel module compiled against the latest DSP/BIOS v6.21.01.16 and just wanted to share some of the changes/problems that I found during the process.
1. ti.sdo.io (IPC) is no longer provided by DSP/BIOS > 6.x. IPC is now bundled with CCS4. For our purposes I made a tarball of the /ipc_1_00_00_40 directory provided with CCS4 and made a ti-ipc_1.00.00.40.bb recipe that ti-dsplink recipe depends on. http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/sysbios/6_21_01_16/exports/docs/Bios_6_21_01_16_release_notes.html 2. Modified ti-dsplink_1.64.bb to export XDCPATH as per DSP/BIOS 6.x release notes at: http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/sysbios/6_21_01_16/exports/docs/docs/Bios_Getting_Started_Guide.pdf 3. ti-dsplink_1.64.bb recipe has a hard-coded DSP/BIOS version in it that gets passed into a perl configuration script (config/bin/dsplinkcfg.pl). I changed the version 5XX to 6XX so that the generated Makefiles would compile against the new BIOS, which is fine for us but probably isn't adequate for angstrom. 4. Compiling the dsp library and dsp samples, I needed to pass in extra environment variables XDCTOOLS_DIR and BASE_IPC because these were not being detected automatically. Here is a patch showing what I did, but it needs more work before inclusion into angstrom: Index: recipes/ti/ti-dspbios_6.21.01.16.bb =================================================================== --- recipes/ti/ti-dspbios_6.21.01.16.bb (revision 0) +++ recipes/ti/ti-dspbios_6.21.01.16.bb (revision 52656) @@ -0,0 +1,13 @@ +require ti-dspbios.inc + +DESCRIPTION = "TI DSP/BIOS v6 Kernel" +HOMEPAGE = "http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/bios/sysbios";
