- Subject: [ECOS] FLASH: driver init failed: Unknown error
Hi all:
I am trying to boot on a MX31 with NAND flash. In a porting effort, i
actually modified some files and then when i was trying to load the
image to RAM using JTAG and then execute it, i got the following on
running the image.
++Inside flash_hwr_init
2: Use "factive" to select a boot type such as NAND|NOR|MMC|...
FLASH: driver init failed: Unknown error
Sorry, FLASH config exceeds available space in FIS directory.
I went to trace the origin of the error message and it seems the
flash_hwr_init() is failing because of some reason. APparently , it
ends up in the
int flash_hwr_init(void)
{
??? diag_printf("Inside flash_hwr_init \n");
??? if (IS_BOOTING_FROM_NOR() || IS_FIS_FROM_NOR()) {
#ifdef MXCFLASH_SELECT_NOR
??????? return norflash_hwr_init();
#else
??????? return -1;
#endif
??? } else if (IS_BOOTING_FROM_NAND() || IS_FIS_FROM_NAND()) {
??????? return nandflash_hwr_init();
??? } else if (IS_BOOTING_FROM_MMC() || IS_FIS_FROM_MMC()){
#ifdef MXCFLASH_SELECT_MMC
??????? return mmcflash_hwr_init();
#else
??????? return -1;
#endif
??? } else {
??????? if (!mxc_flash_warning_done)
??????????? mxc_flash_warning_done = 1;
??????? diag_printf("2: Use \"factive\" to select a boot type such as
NAND|NOR|MMC|...\n");
??????? return -1;
??? }
}
I am landing into the third "else" block. I don't know the reasons for
the same. It seems i have modified some startup code. Would it be
because i have modified something in the platform_setup.h
Thanks in Advance,
Alfred.
