Dear Otavio Salvador,
The mxsboot now receives the SoC type as parameter to generate binary compatible with the SoC. Currently the NAND support has not been add for i.MX23 as it is not yet supported in U-Boot.
Please fix the NAND support as well, then resubmit.
I won't work on NAND now; first I wish to fix the NAND driver support to later work in boot support.
The patch basically does dd if=u-boot.sb ... bs=512 seek=4 ; any kind of information can be stored in those first four blocks and the mx23 bootrom ignores it, so what's the gain of this?
Well, it works fine for users. A good gain in my opinion.
How is a simple documented dd if=... different? It's the same on imx, you have to dd u-boot.imx with some offset.
I wonder, will MX28 bootrom ignore them as well? Then maybe we can get rid of all this SD-specific junk.
Did not test but MX28 expects a BCB data structure (as said in 12.11.2
- MX28RM) while MX23 does not. So I think MX28 won't work without the
BCB.
Fabio?
Furthermore, I'd like to see all of this reworked as another plugin for mkimage.
Yes; it would be a good long term solution but I don't want to hold it due any of above reasons. It works fine so improvements can be done later.
We already have a solution:
dd if=u-boot.sb of=/dev/sdX1 bs=512 seek=4
I think this is enough for now, until all is fixed in proper sequence. That is, NAND driver and only after that, mxsboot for NAND _and_ SD . For now, let's hold off this patch, add the above dd stuff into documentation (doc/README.mx23) and then when all is ready, fix it all properly please.
