**** BEGIN LOGGING AT Fri Apr 18 02:59:59 2014 Apr 18 10:42:12 ant_work, Hello. regarding collie - I would think that the MSB chip is soldered in improper/untypical way. However the working jedec detection fails this theory. Apr 18 11:02:00 hi lumag Apr 18 11:02:05 hello Apr 18 11:02:16 well, it is even more strange Apr 18 11:02:44 I can read at offset 0x0 and 0x1(*4) to get the CFI MFR and ID Apr 18 11:03:00 and I get valid result b000b0... Apr 18 11:03:20 at offset 0x10 (*4) I get ffff0051 Apr 18 11:06:26 I was thinking the MSC0 is not properly set but it doesn't seem the case Apr 18 11:09:22 fwiw in the appendix the CFI is showed as 'ROM'...maybe this table has been flashed on one single chip? Apr 18 11:09:51 the MFR and ID could be a mirror of the JEDEC id's Apr 18 11:11:19 btw, the service manual has 2 differents part-ID for the chips, even though they are equal Apr 18 11:16:10 there are strange marks on them Apr 18 11:16:12 http://www.tekprosystems.com/images/zaurus/zguts8.jpg Apr 18 11:16:29 and older pcb Apr 18 11:16:30 http://www.tekprosystems.com/images/zaurus/zguts2.jpg Apr 18 11:20:20 lumag: more important, I think there is an issue with reboot on collie...it takes very long Apr 18 11:22:56 I'm booting from CF so maybe it falls in the Russell's remark Apr 18 11:22:58 - Patches 4, 5 need to come before patch 3 to avoid a NULL pointer deref Apr 18 11:22:58 in sa1100_pcmcia_set_timing() (ISTR this function gets called on SA1111 Apr 18 11:22:58 as well.) Apr 18 11:24:03 I'll have some time these next days, ping me if there is smtgh to test Apr 18 13:02:53 lumag: I found references to external doughterboards for similar sa1100 ("itsy") Apr 18 13:03:41 still wondering about locomo's FROM_B(uffer) pin and msc0xx ROM_SEL Apr 18 13:04:05 fwiw there is an unused header in locomo.h Apr 18 13:04:06 31 /* MCS decoder for boot selecting */ Apr 18 13:04:06 32 #define LOCOMO_MCSX0 Apr 18 13:04:08 ... Apr 18 13:05:00 as the same 0x10 address as on sa1100 MSC0 Apr 18 16:25:37 lumag: these are the first CFI entries...
