SB_CONFIG_MCUBOOT_COMPRESSED_IMAGE_SUPPORT can nut use for nRF52833

[loquat]

I work for nRF52833 on NCS2.8.0.

I try to set SB_CONFIG_MCUBOOT_COMPRESSED_IMAGE_SUPPORT=y for sysbuild.

build error is occured.

Maybe there is not enough RAM for mcuboot.
MAX_LZMA_DICT_SIZE=128KB is set and RAM seems to be overflowing.
Please tell me how to solve this problem.

Hi,

That is correct. There is not enough RAM for MCUboot to compress the image on the nRF52833.

As of now, the support status for image compression is only experimental for nRF52840, nRF5340 and nRF54L15 and it is not supported on devices with less RAM than the nRF52840.

Kind regards,
Andreas

That's a pity.
I think compressed images are particularly effective for those with little FLASH (such as nRF52833).
