Starterware/AM4378: Error when compile bootloader project

user4999129
Intellectual 550 points
Part Number: AM4378
Other Parts Discussed in Thread: PRU-ICSS-INDUSTRIAL-SW

Tool/software: Starterware

Hi :

I try to compile bootloader project in starterware for am4378.

My ccs version is 6.1.2, compiler is GNU v4.9.3.

At first, I import the bootloader project. Then import the necessary dependent project and config them as below.

At last, I compile the bootloader ,but there are several errors and warnings as show below.

**** Build of configuration am43xx_boot_mmcsd_debug for project bootloader ****

Is there anyone who have come across this problem that can give a hand?

    Starterware CCS projects for AM437x were only supported in SYSBIOSSDK-IND-SITARA. TI has stopped providing free support for SYSBIOSSDK-IND-AM335x on 31 March 2017 as you can see from the notification here:

    e2e.ti.com/.../580869

    We are currently supporting development only with Processor SDK RTOS and PRU-ICSS-INDUSTRIAL-SW . We recommend that you migrate to this software baseline to get support on TI E2E forums.

    Processor SDK RTOS support for bootloaders is described here and we are happy to support this baseline.
