ok, i'm trying to do something on my MPC8315E-RDB that *should* be really simple, and i'm getting nowhere.
currently on this machine, i have u-boot in NOR flash, and it's old but it will still boot the other images also stored in NOR flash: U-Boot 1.3.0-rc2 (Mar 21 2008 - 16:00:02) MPC83XX i just built a new image from the current poky repo for precisely this target, and my generated artifacts include the newer u-boot binary image: -rwxr-xr-x. 2 rpjday rpjday 423964 Jul 5 06:46 u-boot-mpc8315e-rdb-v2016.03+gitAUTOINC+df61a74e68-r0.bin rather than immediately write it to flash, i'd like to download and test it first, and everything i've seen suggests i should be able to: => tftp 0x100000 u-boot-mpc8315e-rdb-v2016.03+gitAUTOINC+df61a74e68-r0.bin => go 0x100000 well, the downloading seems to work fine: => tftp 0x100000 u-boot-mpc8315e-rdb-v2016.03+gitAUTOINC+df61a74e68-r0.bin Speed: 1000, full duplex Using eTSEC0 device TFTP from server 192.168.1.13; our IP address is 192.168.1.127 Filename 'u-boot-mpc8315e-rdb-v2016.03+gitAUTOINC+df61a74e68-r0.bin'. Load address: 0x100000 Loading: ############################# done Bytes transferred = 423964 (6781c hex) => so the number of bytes transferred is correct. and then bad things happen: => go 0x100000 ## Starting application at 0x00100000 ...
