Flashrom stuck using 100% cpu while probing for a chip
by GatoLoko 28 Apr '14

28 Apr '14

I've tried to run flashrom -V to see if it could identify the chip on my new board (AsRock M3A-GLAN), and it got stuck while probing for the first chip. I've tried commenting out that specific chip (AMIC A25L05PT) and then it gets stuck on the next one. Then commented out all AMIC chips, and it got stuck on the next one (the first ATMEL on the list) I've tried with an older flashrom (0.9.2-r1141). It skipped some AMD chips, then got stuck on AMIC again. Talked with "tlt" and "stefanct" on irc and they asked for a strace and a gdb backtrace. Strace produced no results. Gdb log is attached. "stefanct" tried and reproduced it on a machine with nicintel_spi, but warned it was with an unsupported nic: http://paste.flashrom.org/view.php?id=738 -- GatoLoko

I have a TUMPA Lite edition it is FTDI Based Board similar to TUMPA/FT232H, but single channel: http://www.tiaowiki.com/w/TIAO_USB_Multi_Protocol_Adapter_Lite_User's_Manual You can build one from upper link, or buy cheap on ebay.
