求问,AM335x在MMC0上最大可支持多大容量的TF卡?目前存在链接内情况www.deyisupport.com/.../137010.aspx
系统从TF卡启动,手动往eMMC烧写系统时会报kmalloc错误,TF卡为Sandisk 32G class10,出现错误几率将近70%。换用4G class4卡以后没有出现问题。请问这个跟链接内错误有关联吗?

mmc0 boot有4GB的限制。
• MMC0 supports booting from the MMC/SD card cage and also supports booting from eMMC/eSD/managed NAND memory devices with less than 4GB capacity.
• MMC1 supports booting from eMMC/eSD/managed NAND memory device with 4GB capacity or greater.

可是TF卡槽设计在MMC0上用32G的卡是可以启动起来的,只不过在往eMMC烧写系统时会内存申请报错。TF卡容量过大会影响内存申请吗?有点迷糊还希望能指点一下,谢谢了
TF卡的容量和内存是没有任何关系的,你有换过别的牌子的试试么?
同样是32G的其他牌子的卡没有,4G的卡有多个牌子,试过都没问题,可是这样的话报错也不应该至于是内存申请错误呀....具体错误信息可以看之前的链接
