 This means that we can store the kernel image at 0xB0440000, and that we can use the area from 0xB0020000 to 0xB043FFFF (4224 KiB) for JFFS2.
-By using the existing brnboot instead of u-boot, we avoid the risk of bricking the device. brnboot is accessible via the serial interface, but it also offers an [[toh:arcadyan:arv752dpw#flash.to.openwrt.without.opening.the.device | emergency web interface]] on [[http://192.168.1.1/]] when it doesn't find a //valid// code image in any of the two "Code Image" sections in flash.
