Hi Matteo,

Thanks for your reply!

Could you explain a bit more why to change & for && ?

Wouldn't changing:
if(!readw(host->base + GLAMO_REG_MMC_RB_STAT1) & GLAMO_STAT1_MMC_IDLE)

to:
if(!readw(host->base + GLAMO_REG_MMC_RB_STAT1) && GLAMO_STAT1_MMC_IDLE)

Change the logic of the program?

In the first case the "if" statement would be true if either
readw(host->base + GLAMO_REG_MMC_RB_STAT1) is false, or
GLAMO_STAT1_MMC_IDLE is true.

in the second case the "if" statement would be true if
eadw(host->base + GLAMO_REG_MMC_RB_STAT1) is false and
GLAMO_STAT1_MMC_IDLE is true.

I can't tell from the source code what the intention of the program was.

Thanks for your time!

Kind regards.

Yes, the GTA02 is still my one and only mobile phone ;-)
