Note that we disabled NFS for everyone recently (I think it will be default off in v2024.01), and CMD_TFTPSRV isn't enabled by default for anyone. At this point, anything which could have an impact on size should be in Kconfig so examining the whole .config file might give other suggestions on what could be disabled for size. > > 2.

In general, I would suggest disabling CMD_LICENSE before disabling CMD_DATE as well. But I see that's already done here. The same would be with CONFIG_BOOTM_VXWORKS, but that's also off here. Maybe disable the memtest command? It's not that good of a tester as it is. Or maybe CONFIG_MMC_VERBOSE=y can be turned off? -- Tom
