Had a quick look for ya. Try changing packages\hal\mips\ap48\v2_0\misc\redboot_ROM.ecm

Replace cdl_option, CYGHWR_DEVS_FLASH_AMD_AM29LV160 with CYGHWR_DEVS_FLASH_AMD_AM29LV320D

This didn't help. The same error.

Maybe this has to do with UrJTAG ?

Where do the values in flash layout come from ?

        block_size : 0x10000 * CYGNUM_FLASH_INTERLEAVE,

My redboot source is custom so i do things very differently.

You could try this hackish way,

build as usual, cd into the build dir, take a look at ecos.ecc. see if you can find your flash part and if its enabled

should be something like

cdl_option CYGHWR_DEVS_FLASH_AMD_AM29LV160 {
    # Flavor: bool
    # No user value, uncomment the following line to provide one.
    # user_value 0
    # The inferred value should not be edited directly.
    inferred_value 1
    # value_source inferred
    # Default value: 0
};

# AMD AM29LV320 flash memory support
# When this option is enabled, the AMD flash driver will be
# able to recognize and handle the AMD29LV320
# part in the family.
#
cdl_option CYGHWR_DEVS_FLASH_AMD_AM29LV320D {
    # Flavor: bool
    # user_value 0
    # value_source default
    # Default value: 0

replace it with

cdl_option CYGHWR_DEVS_FLASH_AMD_AM29LV160 {
    # Flavor: bool
    # No user value, uncomment the following line to provide one.
    # user_value 0
    # value_source default
    # Default value: 0
};

# AMD AM29LV320 flash memory support
# When this option is enabled, the AMD flash driver will be
# able to recognize and handle the AMD29LV320
# part in the family.
#
cdl_option CYGHWR_DEVS_FLASH_AMD_AM29LV320D {
    # Flavor: bool
    user_value 1
    # value_source user
    # Default value: 0

# cd ..
# ECOS_REPOSITORY=`pwd`/ecos-2.0/packages export ECOS_REPOSITORY
# PATH=`pwd`/gnutools/mipsisa32-elf/bin:$PATH export PATH
# PATH=`pwd`/ecos-2.0/tools/bin:$PATH export PATH
# cd [BUILD_DIR]

delete everything except ecos.ecc

# ecosconfig tree
# make
# cd install/bin
# mipsisa32-elf-objcopy -O binary redboot.elf redboot.rom

I cant guarantee it will work though.

routednbooted, please share your redboot source or a patch. It's interesting to have a look.

Everything was done exactly as said in post #6.
It became clear from disassembling rom image that there is absolutely no difference between what is done in post #2 and post #6.

Following is the diff of the disassembled rom image between pristine source and routednbooted's advice:

SOLVED

The problem was with device id detection. Hardcoding solved the problem.
