Hello everyone! I am a newbie and trying to run the barebox on BeagleBoard-Xm rev.C with 512MB DDR on board. To support 512MB I did the following: 1) file: arm/boards/beagle/board.c, func: beagle_mem_init(), change line 85: beagle_mem_init(void) { //omap_add_ram0(SZ_128M); omap_add_ram0(SZ_512M); } 2) file: arm/boards/beagle/lowlevel.c, func: sdrc_init(), change line 127: //writel(0x02584099, OMAP3_SDRC_REG(MCFG_0)); writel(0x02590099, OMAP3_SDRC_REG(MCFG_0)); // to add 512MB support on CS0 Then launch barebox and send command - memtest, which return error: "FAILURE: Address bit stuck high @ 0x90000000: expected 0xaaaaaaaa, actual 0x7fffffff", but commands "memset" writes data to the address 0x90000000 correct, what I did not so? Best Regards, Valeriy Nyrov.
