When I use
fw_setenv test_name test_value the Red Pitaya doesn't save the variable to EEPROM. I can verify this by subsequently calling
fw_printenv and noticing that
test_name has not been set.
What gives?
My
/etc/fw_env.config file:
Code: Select all
# Configuration file for fw_(printenv/setenv) utility.
# Up to two entries are valid, in this case the redundant
# environment sector is assumed present.
# Notice, that the "Number of sectors" is ignored on NOR and SPI-dataflash.
# Futhermore, if the Flash sector size is ommitted, this value is assumed to
# be the same as the Environment size, which is valid for NOR and SPI-dataflash
# MTD device name Device offset Environment size
/sys/bus/i2c/devices/0-0050/eeprom 0x1800 0x0400
This is also an issue when I try to set the EEPROM variables directly from u-boot using
setenv temp_name temp_value and then
saveenv. After a reboot,
printenv doesn't include
temp_name.
