[U-Boot] Unable to decompress files greater than 500 MB

[Zakir Ahmed]

Hello Schocher,

Thanks for your response.

This is custom board which uses ARM Cortex- A15 processor.
RAM is 2GB.
I run loading uboot at 
1536 MB (0x60000000) to avoid overwriting uboot code. 
Compressed Image at 0x47400000 -> 1140 MB (Compressed Image < 200 MB)
Uncompressed Image at 0x0C000000 -> I have tested this at different
addresses starting from 0xA000 till 0x0C000000. Same issue is seen

On which board is this and how much RAM do you have?
How looks your memory map?
In which way does it fail?

I just speculate now ... you may overwrite U-Boot Code /stack malloc space ?
