<GXL_BL2> arg, been fiddling for awhile. I can execute p212's BL2 (aarch64) from BL1.
<GXL_BL2> but I cannot execute khadas-vim or lepotato or my bl2 from BL1. they are all aarch32
<GXL_BL2> entry point seems to be 0x1000 for all bl2 but seems to be not doing anything if bl2 is aarch32. argggg
<GXL_BL2> anyone has p212 BL2 v2019 (aarch32)?

<f_> GXL_BL2: Well if p212 bl2 works why not use it?
<f_> You'll probably need to transplant some things from your OG BL2 dump though.

<GXL_BL2> @f_ afaik, there are too many things that i need to transplant from og bl2. i think bl3x are all encrypted and bl2 is the one who load/decrypts/run them.
<GXL_BL2> if i make my og bl2 work, i can just make few more byte patches for SB and ARB. that will be end of work with bl2
<f_> GXL_BL2: yes, but the keys are not in the bl2 binary
<f_> all you'd need is to transplant acs.bin and eventually bl21
