Comments on: 3.80 and Pandora http://my.malloc.us/silverspring/2007/12/380-and-pandora/ SilverSpring's bunch of random PSP stuff...

If read_eeprom returns a negative number (which it would if sceSysconCmdExec failed) it means it failed. Any other value would mean it succeeded (and would have the correct value for the eeprom read). Anyway, it was meant to be a direct replacement for the sceSysconBatteryReadNVM/sceSysconBatteryWriteNVM functions which were taken out of the firmware starting from 3.80. Refer to http://forums.ps2dev.org/viewtopic.php?p=57634#57634 where nem posted the prototypes (the function names werent known when that post was made so they're labelled sceSyscon_driver_68EF0BEF/sceSyscon_driver_1165C864). This code was meant for apps using the above functions to be able to work in 3.80+. Ie. pandora apps from cory1492, hellcat, et al. So I would have to make sure the prototypes stayed the same as the original functions and that the code functioned exactly the same as the originals. What do you mean might not notice?

I have notice in the code of read_eeprom, may be a strange behavior if sceSysconCmdExec returns an error, the caller may not notice. I would suggest to do something like: int read_eeprom(u8 addr, u16 * value) { int res; u8 param[0x60]; if (addr>0x7F) return(0x80000102); param[0x0C] = 0x74; // read battery eeprom command param[0x0D] = 3; // tx packet length // tx data param[0x0E] = addr; res = sceSysconCmdExec(param, 0); if (res Hi Silverspring,

int read_eeprom(u8 addr, u16 * value)
{

u8 param[0x60];

if (addr>0x7F) return(0×80000102);

param[0x0C] = 0×74; // read battery eeprom command
param[0x0D] = 3; // tx packet length

// tx data
param[0x0E] = addr;
res = sceSysconCmdExec(param, 0);

I'd like to have that working on 3.80 as well ;-) Propper credits would be given, of course! Hi! :-)
