<PaulFertser> ts_: please never paste to channel more than 2 lines, use some pastebin
<PaulFertser> ts_: and you didn't answer my question.
<ts_> i using hexchat
<PaulFertser> ts_: so what?
<ts_> poor english
<ts_> let me see
<ts_> 0x00f80000 is u-boot.bin?
<PaulFertser> ts_: what does target memory map say about address 0x33f80000? Why are you trying to load anything there?
<ts_> SDRAM
<ts_> datasheet show that is SDRAM
<PaulFertser> ts_: did you init SDRAM controller accordingly before trying to upload anything there?
<ts_> I see the Internet says that init_2440 is needed
<ts_> but the command is invalid
<ts_> or i copy the uboot to 0x0000000?Doesn’t need to be initialized?
<PaulFertser> ts_: what's at 0x0000000?
<ts_> boot internal
<ts_> sram
<PaulFertser> ts_: if SRAM is big enough for your purpose and it's really there then you can probably upload something.
<ts_> thanks
