Hi, Chris, For the init value of "next_pbl_cmd", there was a patch at below link can be used: http://lists.denx.de/pipermail/u-boot/2013-March/150260.html
this patch with your modification below should can meet your requirement: > -static unsigned char mem_buf[600000]; > +static unsigned char mem_buf[1000000]; Best Regards, Shaohui Xie > -----Original Message----- > From: Chris Packham [mailto:judge.pack...@gmail.com] > Sent: Monday, May 27, 2013 6:52 AM > To: Fleming Andy-AFLEMING > Cc: Xie Shaohui-B21989; u-boot@lists.denx.de; Chris Packham > Subject: [PATCH] powerpc/CoreNet: Allow pbl images to take u-boot > images != 512K > > From: Chris Packham <chris.pack...@alliedtelesis.co.nz> > > Instead of assuming that SYS_TEXT_BASE is 0xFFF80000 calculate the > initial pbl command offset by subtracting the image size from the top of > the 24-bit address range.
