AT91SAM9G45 Errata
ROM Code: SDCARD
ISI: Codec Path is disabled
LCDC: LCD formula to compute LCD Pixel Clock
HSMCI: R1B Busy Timing
On Reset, the faulty ROM code will copy the fixed ROM code in SRAM and launch it. The con-
nexion through USB to the SAM-BA monitor will work.
Note:
SDCARD boot is not supported.
None
The ISI Codec path is disabled after the capture of each frame and so requires to be enabled
before the capture of the next frame. This may lead to discarding some frames if the frame rate
is high.
None
The LCD formula to compute the LCD pixel clock is system_clock/2*(CLKVAL+1) instead of
system_clock/(CLKVAL+1).
None
Busy line is sampled 2 clock cycles after the command End Bit when the R1B response type is
expected.
This timing is not strictly defined in SD mode.
This timing is defined in MMC Specification V4.3. (R1B busy Timing)
The user must poll the D0 (busy line) through the PIO Controller and wait for a rising edge on
that line.
