Hi,
I sometimes see this weird message
.*** Warning - bad CRC, using default environment
instead of
.raspi_read: from:30000 len:1000
appearing at boot (9th line).
What could cause this to happen? Is it an error ?
I've seen it on working devices and that doesn't seem to cause a problem.
For example, https://openwrt.org/toh/asus/rt-g32 section "OEM bootlog"
This is a full extract of the output while the device boots :

Please choose the operation:
1: Load system code to SDRAM via TFTP.
2: Load system code then write to Flash via TFTP.
3: Boot system code via Flash (default).
4: Entr boot command line interface.
7: Load Boot Loader code then write to Flash via Serial.
9: Load Boot Loader code then write to Flash via TFTP.
Many thanks !
