How much of the onchip RAM does the OMAP-L138 ROM bootloader use when bootloading in MMC/SD mode? The bootloader appnote mentions the RAM usage in non-NAND modes as 2KB and in NAND-Boot mode as 8KB.
"9.1 General Comments
• Non-NAND Memory Usage: The bootloader uses 2 KB of ARM local RAM starting from 0xFFFF0000. This memory should not be used by any initialized section of the user application."
"9.6 NAND-Boot Modes
• The bootloader uses 8 KB of ARM local RAM starting from 0xFFFF0000. This memory should not be
used by any initialized section of the user application."
However, we have confirmed through testing in MMC/SD-boot mode that the ROM bootloader is writing data at 0xFFFF1000 (4KB from start) which is not consistent with the document.
What is the actual range or onchip RAM that the bootloader may affect during MMC/SD boot mode?
