When I power on the board, nothing happened on serial console but when I press reset button (or if I reset board using JTAG, to board boot properly. With NAND Numonyx NAND02G-B2D, it works well on power on but with Micron MT29F2G08ABBEAH4, coldboot does not work, I have to press RESET button. The specs seem to be similar. The only difference is a device initialization for Micron that says that host must wait 100us after VCC is applied before sending Reset (FFh) command. Where have I to place the wait loop ? At the beginning of In PLATFORM_SETUP1 macro (.macro _platform_setup1) in hal_platform_setup.h or anywhere else ? Test is done on boards with i.MX27 CPUs that have different revision (200951, 201209). And I know that newer revison (starting from 2012) can freeze at boot due to bug in PLL circuit. Do you have any other leads for me ? Thank you for your help. Gaëtan Carlier. ps : Of course, I have tried MT29 NAND on several board (that works with NAND02G chip) but same result. -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
