Hi,
I'm using 52255 for current project. It's working only with internal flash and SRAM, and works fine.
When I try to re-arrange flash blocks for putting something like bootloader in front of normal program, problem happened.
The original flash blocks like following
# original settings
## intflash (RX): ORIGIN = 0x00000000, LENGTH = 0x00080000
## sram (RW): ORIGIN = 0x20000000, LENGTH = 0x00010000
vectorrom (RX): ORIGIN = 0x00000000, LENGTH = 0x00000400
cfmprotrom (RX): ORIGIN = 0x00000400, LENGTH = 0x00000020
rom (RX): ORIGIN = 0x00000420, LENGTH = 0x0007FBE0
ram (RW): ORIGIN = 0x20000000, LENGTH = 0x00010000
I put bootloader in first 64KB like this
## intflash (RX): ORIGIN = 0x00000000, LENGTH = 0x00080000
## sram (RW): ORIGIN = 0x20000000, LENGTH = 0x00010000
bootloader (RX): ORIGIN = 0x00000000, LENGTH = 0x00010000 # bootloader
vectorrom (RX): ORIGIN = 0x00010000, LENGTH = 0x00000400
cfmprotrom (RX): ORIGIN = 0x00010400, LENGTH = 0x00000020
rom (RX): ORIGIN = 0x00010430, LENGTH = 0x0006FBD0 # Code + Const data
ram (RW): ORIGIN = 0x20000000, LENGTH = 0x00010000 # SRAM - RW data
I create another project for bootloader, but I just put an direct jump to normal program start for testing.
Program stopped in initializing PHY.
There is an loop for auto-negotiate with PHY in BSP of MQX.
Normally it works fine. But it stuck when I shift all program at 0x00010000.
Is that anything I missed when moving blocks?
Please help, I've try days for this, I cannot understand why the same code cause different results.
Thanks!
