Yes. Which image do you start? It seems you are trying to start barebox.bin. > barebox.bin and barebox-freescale-mx28evk-2nd.img It should be images/barebox-freescale-mx28evk-2nd.img instead. The image should be linked to 0x0, that is right. The code is position independent though and the full barebox relocates itself to the end of the available SDRAM automatically. TEXT_BASE is not relevant here. The start symbol is still 0x00000000 even I change TEXT_BASE in menuconfig. my board have 64MiB ram. Modified board. Very cheap one, just 33€. :D EasyARM-i.MX283A http://www.zlg.cn/ipc/ipc/product/id/92.html http://www.zlg.cn/ipc/down/down/id/92.html This board has a LCD(480*800?), I want to test font support on this board. The sch is here: https://drive.google.com/open?id=1_3xW7nfQ6p9tnkjZEDK9vZiLlUnat25K There are many pcf fonts here: https://www.netsarang.com/download/main.html and maybe use code from freetype? http://www.freetype.org/ Sascha -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 |
