<Grimler> Hi there, I'm working on updating u-boot in SPI flash for the exynos5 chromebooks. I have exynos5420-peach-pit, and am testing on that. Has anyone ever read out the SPI flash on one of the exynos5250 chromebooks? If yes, could you please share it so I can analyze SPL and u-boot in it?
<Grimler> I have managed to connect to the serial port of the device, but so far I get 0 output or lifesigns after writing another SPL and u-boot to SPI flash. Pretty sure some modifications (like addition of a hashsum) is needed before flashing. Comparing with more stock SPI images would help understanding what is needed
<Grimler> Aha! It is provided in this blog post: http://www.de7ec7ed.com/2013/05/extracted-firmware-samsung-chromebook.html so now I have it, great!
