(kermit mode or ymodem mode) NAND flash type. It depends on what commands do you have? Yes, it would be best to use load command to get the data via serial line, store it in RAM and then flash it on persistent memory. How do you access NVRAM? (Is it really this memory - not some Parallel NAND, SPI-NOR, OneNAND)? If it has a custom driver ,then you may want to look for 'cp' or other command. > > Regards, > Alex > > > _______________________________________________ > U-Boot mailing list > U-Boot at lists.denx.de > https://lists.denx.de/listinfo/u-boot Best regards, Lukasz Majewski -- DENX Software Engineering GmbH, Managing Director: Wolfgang Denk HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: wd at denx.de -------------- next part -------------- A non-text attachment was scrubbed...
