I assume you have a linux boot?
A number of solutions to blank SPI, if you have mtd-utils installed...nandtest /dev/mtdblock0
Takes about 15m, blanks SPI
OR
dd if=/dev/zero of=/dev/mtdblock0 bs=1M count=16
lots of advice shows writing /dev/mtd0, whatever lsblk shows is the right device
writing SPI is slow, be patient
