Hello all:
I have read most of the thread, and now I'm trying to unlock the bootloader of my MA5671A, but without success. I have built a custom adapter for SFP with a molex socket I bought on aliexpress. I followed instructions about pinout to my USB TTL adapter:
pin 2: SFP Transmit (USB TTL Receive)
pin 7: SFP Receive, (USB TTL Transmit)
pin 10: GND. Used for sfp power on
pin 15 & pin 16: VCC 3.3 volts (USB TTL 3.3 volts).
I can see the bootloader on teraterm or putty:
U-Boot 2011.12-lantiq-gpon-1.2.24 (Nov 03 2014 - 22:46:28), Build: falcon_sfp_linux
Board: SFP
DRAM: 64 MiB
Now running in RAM - U-Boot a
ROM: V1.1.4
ROM: CFG 0x00000006
ROM: SFLASH-4hw fuse format 1
I can stop bootloader process (shorting contacts 4 and 5 of the flash memory), then I press 7 and send file 1224ABORT.bin over xmodem. But, after that I can't stop bootloader with control-c, and I can't reach uboot prompt (like other people has commnet). I think I'm missing some step:
FALCON =>
I bought the module on ebay and I cant tell if its broken. Some thing strange is the bootloader text does not print boot address. It says U-Boot a... but does not print memory adress...
Now running in RAM - U-Boot a ยท
If I connect the sfp to an tp-link MC220L I can ssh into the module, but with restricted mini-shell, so the sfp seems to boot ok, but I can't tell if it connecto to the OLT...
Any ideas or suggestions will be much apreciated. Thanks in advance.
