This device works a few mounth and start to some freezes sometimes so at the moment stop booting totally. I do the following:
1. I heated up S3C2416 area by air gun up to 50-70 deegrees and device wake up to work, but only for two weeks.
2. I resolder S3C2416 but this not helps (black screen).
3. I look to J801 to have a boot log messages, but have't any activity on this connector. It cannot help.
4. I used JetLink (J-Link clone) and OpenOCD v0.12.0 to connect to S3C2416 (see attach). However, this a bit help me to have a successed log, but nTRST pin not functional under the JetLink and I cannot undestand how to configure it in openocd.cfg file. So, SoC cannot be halted.
5. I prepared my old PC with LPT port to try H-JTAG with Wiggler adapter. Not yet tried...
Please, help me to restore the device. Hope, this is a NAND need to be replaced. I have the T56 programmer and can reflash the new SAMSUNG K9F1G08U0E chip by resoldering it directly. I need a full dump (~130Mb) for DSO5202BM or any futher suggestions...
