Hi Balaji,
I am having the following boot requirements:
Boot software will be flashed in to PROM, which should start from PROM and copy the application software which is flahsed in other flash device in different address space. The processor is LEON3FT.
is current release of U-Boot supports LEON3FT architecture, please provide with details and link to get start
Actually I don't know much about the Leon line of CPUs, but I see that we have three configurations using a Leon CPU: gr_cpci_ax2000, gr_ep2s60, grsim and gr_xc3s_1500. I put the maintainer of these boards on CC, so maybe he can answer that.
Cheers Detlev
Thank you for CC:ing me Detlev.
As Detlev points out there are three BSPs available. Since the LEON3 is a SOC it is hard to support all different configurations on a board, so the BSPs intention is to support the template design of GRLIB.
The LEON3FT is not supported in the current u-boot available in the sparc git repository at denx.de. Some extra steps must be taken when running the fault-tolerant LEON3, one must clear memory and registered for example so that the CRCs of the registers are correct.
I have a version that supports LEON3FT available at ftp://ftp.gaisler.com/u-boot/u-boot-sparc-vxworks-1.0.0.tar.gz, currently I'm working with generating patches for the LEON3 CPU/boards, I have reworked some parts of the current LEON port. I suggest you wait one day or so until I push the patches onto the SPARC-u-boot git repo, after that I will also add the LEON3FT patches. In the meanwhile you can try the FTP link.
