Where do I find oldlzma utility? The current one produces an unbootable
image:
% objcopy -S -O binary kernel kernel.kbin
% lzma kernel.kbin
% mkimage -A arm -O FreeBSD -T kernel -C lzma -a 0x40000100 -e 0x40000100
-n rt1310 -d kernel.kbin.lzma kernel.kbin.lzma.u-boot
Image Name: rt1310
Created: Sat Aug 11 09:06:27 2018
Image Type: ARM FreeBSD Kernel Image (lzma compressed)
Data Size: 1317305 Bytes = 1286.43 KiB = 1.26 MiB
Load Address: 40000100
Entry Point: 40000100
% scp kernel.kbin.lzma.u-boot tftp:tftpboot
...
RT2860-EVB# bootm
## Booting image at 00800000 ...
Image Name: rt1310
Image Type: ARM Unknown OS Kernel Image (lzma compressed)
Data Size: 1317305 Bytes = 1.3 MB
Load Address: 40000100
Entry Point: 40000100
Verifying Checksum ... OK
Uncompressing Kernel Image ... LZMA ERROR 1 - must RESET board to recover
OK
I see you have 'oldlzma' and online instructions use an oldlzma command...
