Fel connects but data not transferring - new issue

[sridharrajagopal]

I'm facing the same issue. One chip successfully flashed, but the other is giving this problem. I modified the scripts to add verbosity to sunxi-fel, and saw that this is the command that fails:

sudo sunxi-fel --verbose spl .new/firmware/images/sunxi-spl.bin
Enabling the L2 cache
Stack pointers: sp_irq=0x00002000, sp=0x00005DF8
Reading the MMU translation table from 0x00008000
Disabling I-cache, MMU and branch prediction... done.
=> Executing the SPL... done.
usb_bulk_send() ERROR -7: Operation timed out

I've tried attaching the chip to a powered USB hub, but still have the same issue.

Thanks,
Sridhar

Referring to linux-sunxi/sunxi-tools#100 , I built sunxi-tools from source code, and tried

sudo ./sunxi-fel --verbose spl bin/uart0-helloworld-sdboot.sunxi
found DT name in SPL header:
Enabling the L2 cache
Stack pointers: sp_irq=0x00002000, sp=0x00005DF8
Reading the MMU translation table from 0x00008000

Setting write-combine mapping for DRAM.
Setting cached mapping for BROM.
Writing back the MMU translation table.

which completed.
