The SDK for the LS1021A-IoT is contained in a .rar archive file (LS1021A-IoT-SDK-Yocto-1.8.rar). When I attempt to open and extract this archive file, the result is 4 separate files, ending in the .bin extension:


yocto-sdk1.8-20150715.iso_aa.bin (approximately 1.15 GB in size)

yocto-sdk1.8-20150715.iso_ab.bin (approximately 1.15 GB in size)

yocto-sdk1.8-20150715.iso_ac.bin (approximately 1.15 GB in size)

yocto-sdk1.8-20150715.iso_ad.bin (approximately 800 MB in size)


The 7zip utility can further open the file "yocto-sdk1.8-20150715.iso_aa.bin" - it contains several other files and folders:


ls1021a-oobe (folder)

sdk_documentation (folder)







When I try to run the "install" script (from a Linux terminal), I receive an error message stating that "your ISO is incomplete". I suspect that the file "yocto-sdk1.8-20150715.iso_aa.bin" is the first piece of a larger .iso file, with the other pieces being formed by the files ending in _ab.bin, _ac.bin, and _ad.bin.


How do I merge the 4 .bin files back together in order to obtain the complete .iso image for the LS1021A-IoT SDK? Or alternatively, can you just provide me with the complete SDK for the LS1021A-IoT?
