Using L1 Instruction ROM in BF592

i use the bf592 and the GCC elf Toolchain. At the Moment my main problem is, that the Instruction memory is too small. The easiest way would be, to save some of my .text into the ROM. I already edited the linker script and it the LDR and ELF files looks correct (checked with objdump and ldrviewer).  I'am booting in SPI Slave Mode.


So is there a way to write into the ROM? I already managed to get these informations:

- Instruction ROM can be used for instructions and there are already some functions.

- Instruction (L1 ROM) can be used to boot from (111 boot mode)

- It can be written with clpd


Due to the fact, that i have full access to the core it should be possible to write the ROM with an application. If it is possible, then please tell me how.


Many thanks in advance for your help.
