Hello,
I am encountering some issues trying to read a Pm25LV512 SPI flash from a small LCD monitor, really got stuck at this point.
Hardware:
- Pm25LV512 attached to a Weltrend WT8871 video IC
- Arduino UNO R3 with 16u2 USB<>Serial converter
- CD4050 to convert 5v to 3v3
- Used the schematic provided on http://flashrom.org/Serprog/Arduino_flasher
to interface the chip
- Tried "in-circuit" programming without removing the chip from the board
- Wire length of less than 8cm.
Software:
- Latest serprog-duino from git
- Tried with flashrom v0.9.6.1-r1563
- And with flashrom v0.9.7-r1711
- Ubuntu 14.04 64bit
I really appreciate any help I could get and can provide any info/logs needed.
The result looks as if you are reading random data... either your connections are wrong/bad, or the board is disturbing the communication on the SPI bus. See also http://flashrom.org/ISP
Hi Stefan,
I removed the chip from the board, now it is connected directly to the CD4050, i triple checked all the wiring. I think it should be something wrong with the arduino, I know the 25LV512 is functional because the LCD boots fine with it.
I also tried connected it directly to the Arduino, without the CD4050 converter, still the same. I did not damage the chip, the LCD still boots with it.
Thanks !!!

Hello,
I am encountering some issues trying to read a Pm25LV512 SPI flash from a small LCD monitor, really got stuck at this point.
Hardware:
- Pm25LV512 attached to a Weltrend WT8871 video IC
- Arduino UNO R3 with 16u2 USB<>Serial converter
- CD4050 to convert 5v to 3v3
- Used the schematic provided on
http://flashrom.org/Serprog/Arduino_flasher
to interface the chip
- Tried "in-circuit" programming without removing the chip from the board
- Wire length of less than 8cm.
Software:
- Latest serprog-duino from git
- Tried with flashrom v0.9.6.1-r1563
- And with flashrom v0.9.7-r1711
- Ubuntu 14.04 64bit
I really appreciate any help I could get and can provide any info/logs needed.
The result looks as if you are reading random data... either your connections are wrong/bad, or the board is disturbing the communication on the SPI bus. See also http://flashrom.org/ISP
-- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
