Greetings,
This is few minors questions :)
1) I'd like to figure out the content of TS72XX_STATUS register
(0x10800000).
I've got a value of 187 (=0xBB) :
bit 0: JP2 (1 = on)
bit 1: JP3 (1 = on)
bit 2: ???
bit 3: JP4 (1 = off)
bit 4: JP5 (1 = off)
bit 5: ???
bit 6: ???
bit 7: ???
JP6 is bit 0 (1 = on) of 0x22800000.
Is there someting important on the others bits ?
2) The TS72XX_IO16_FEATURES (I mean 0x22400000) is quite not documented
much:
bit 0: AtoD (1 = yes)
bit 1: RS485 (1 = yes)
Inside the drivers/misc/ts_sbcinfo.c there is
...
if (temp & 0x02) {
sbc->RS485 = 1;
sbc->auto485 = 1;
What's auto485 / Is that the half/full duplex feature ?
temp = inw(TS7XXX_MODEL) & 0x07;
sbc->pld_ver = temp & 0x0007;
//set the model number
switch (temp) {
pld_ver should not be read in TS72XX_PLDREV (0x23400000) ??
3) Maybe it has be discussed already on the ML, but how to use the
on-board temperature sensor ??
How to detect if the board has it ?
4) I'm asking the usage of mapping manually the Flash
(arch/arm/mach-ep93xx/mm.c),
Is it only to read the MAC address stored in flash (RedBoot / FIS
directory 0x607E0000) ?
Thanks,
matthieu
