    I have MX25V8035F spi nor flash which I'm trying to erase. Since MX25V8035F is not supported I'm using manual mode to erase/write/read. I'm able to read and erase but there is some memory region that is protected. How can i do an unprotected erase using j-flash spi ?

    I'm trying to connect j-flash spi with my spi nor flash. I'm getting the following error. Connecting to SPI Flash... - VTarget = 3.277V - Read SPI Flash Id = 0xFF FF FF - ERROR: Failed to auto-detect SPI Flash. - Failed to auto-detect SPI Flash. I used logic analyzer to see what's going on and looks like the j flash is sending 0x9f command but the spi is not responding to it. forum.segger.com/index.php/Attachment/5694/
