Tom, Simon,
Is CONFIG_SYS_RELOC_GD_ENV_ADDR really needed on sandbox?
When I try to have a variable environment on emulated SPI flash, the U-Boot binary always crashes: (NOTE: assuming CONFIG_ENV_ADDR == 0) $ dd if=/dev/zero of=./spi.bin bs=1M count=4 $ u-boot -T U-Boot 2020.04-rc2-00015-gc9afef2b1938-dirty (Feb 14 2020 - 10:24:59 +0900)
Model: sandbox DRAM: 128 MiB WDT: Started with servicing (60s timeout) MMC: mmc2: 2 (SD), mmc1: 1 (SD), mmc0: 0 (SD) Loading Environment from SPI Flash... SF: Detected m25p16 with page size 256 Bytes, erase size 64 KiB, total 2 MiB *** Warning - bad CRC, using default environment
Segmentation fault (core dumped)
If this configuration is disabled, panic doesn't happen. I think that it should be turned off in any sandbox*_defconfig.
In addition, please update - doc/arch/sandbox.rst - doc/SPI/README.sandbox-spi Both two still mention already-removed command line option, --spi_sf. It is confusing.
Thanks, -Takahiro Akashi
