It works just fine!!!

新買的Tresend 8G SHDC class4 uSD

本來是想可以灌個好幾個distribution什麼的
結果問題一堆...
結論是，現在只有qtextended/mwest的kernel能支援8G的uSD

u-boot能support 8G uSD
但是bootargs裡不能再放${}之類的變數，u-boot直接把${bootargs}送給kernel，不會展開變數

kernel裡只有QT extended的mwester的kernel可以讀8G uSD的partition table

約081022用debian的install.sh下載的uImage.bin

${rootfstype}和${root}給kernel時竟然沒有被置換掉??

Ok,這才是預期中的結果

符合預期

==>看來是debian的kernel(uImage.bin)沒辦法讀8G uSD的partition table
