Afair files didn’t disappear after rebooting on 230. Lemme see if I can find a copy of the old 230 build to try.
Hi @vchong,
In OP-TEE with AOSP environment from a TA I was trying to write data to a file using “TEE_WriteObjectData”.
I was writing 1KB of data at a time, but after writing around 1.9 MB of data the “TEE_WriteObjectData” panicked showing the below mentioned message.
[ta log] TEE_WriteObjectData SUCCESS written 1913888 bytes
[ta log] TEE_WriteObjectData SUCCESS written 1914912 bytes
[ta log] TEE_WriteObjectData SUCCESS written 1915936 bytes
ERROR: TEE-CORE: request memory size 888 failed
ERROR: USER-TA: Panic 0xffff000c
ERROR: TEE-CORE: TA panicked with code 0xffff000c usr_sp 0x400057b0 usr_lr 0x0
tee_helloworld: TEEC_InvokeCommand failed with code 0xffff3024 origin 0x3
So is there any way to write a large file (say 10MB or so) from the TA ?
Thanks,
Rabi
In your TA’s user_ta_header_defines.h file, try setting TA_STACK_SIZE or TA_DATA_SIZE to (10 * 1024 * 1024).
I have already tried this but that does not solve the problem.
Gone through https://wiki.linaro.org/WorkingGroups/Security/OP-TEE and looks to me need to modify TA’s MMU L1 table to support more memory for the TA as by default it has 1 MB of memory mapped.
Could you please suggest the steps to modify the TA’s MMU L1 Table.
Thanks,
Rabi
The change to the mmu l1 table is not required anymore. I’ve updated the wiki.
Can you try rebuilding with CFG_CORE_UNWIND=y to get a call stack?
Also try adding CFG_CORE_HEAP_SIZE ?= 131072 to plat-hikey/conf.mk.
Note that 10MB is really quite a lot.
Hi @vchong,
After adding CFG_CORE_HEAP_SIZE ?= 131072 to core/arch/arm/plat-hikey/conf.mk the build failed. Also try clean build and that also failed. But if remove the added parameter the build again successful.

I don’t see how adding CFG_CORE_HEAP_SIZE can generate this kind of error. It’s totally unrelated. CFG_CORE_HEAP_SIZE is already defined in optee_os/mk/config.mk in the first place, and you’re just redefining it with a bigger value. Something else must have happened to or changed in the code, with bionic being the prime suspect.
Lemme try a build to see if I can reproduce.
No issue with the build here.
Hi @vchong,
Thanks for the update. For the time being we are OK with the default settings of CFG_CORE_HEAP_SIZE.
Is there any openssl support in the OP-TEE.
We are basically trying to port libcurl with ssl support in OP-TEE. In order to achieve that we need openssl in OP-TEE.
Thanks,
Rabi
openssl is not supported. There were some discussions on how to do it yourself on github.
Do you want it in op-tee core itself, i.e. optee_os, or in the TAs?
For core, there was a proof of concept done a long time ago, but has not been updated since. https://github.com/OP-TEE/optee_os/tree/poc/openssl_cryptolib, https://github.com/OP-TEE/optee_os/issues/340.
For TA, see https://github.com/OP-TEE/optee_os/issues/1303.
I would like to increase the OP-TEE dedicated DDR RAM size which is currently 32 MB. Is it possible and if yes how I can increase that.
Basically I would like to use a 2GB HiKey board instead of 1GB. In 2GB board I would like OP-TEE to use more than 32MB of RAM so that I can execute larger TA on OP-TEE.
@rabindranath-derebac Not sure if this will work, but try changing TDRAM_SIZE in https://github.com/OP-TEE/optee_os/blob/master/core/arch/arm/plat-hikey/platform_config.h#L136 from 16 to some appropriate number of MB sufficient for your use. If it doesn’t work, then, although I’m not a memory expert, it seems like it would touch too many areas of code across different repos to shift the memory mapping around in order to find a larger region to try to make it work, i.e. a huge undertaking that will require lots of effort.
Hi @vchong,
Does HiKey 620 support Hardware decoding?
If yes then which branch of OP-TEE with AOSP we can use for the build.
Thanks,
Rabi

No, I don’t think hardware decode was ever implemented on the 620.

Where can I find the sources for wifi? I’m using the optee_build lemaker with kernel 4.12.0.

I got the latest firmware from: here
But when i use “ifup wlan0” → Cannot find device “wlan0”
With my hikey960 and the optee_build I dont need to do this, I just activate wl18x and wlcore in my defconfig and modify the buildroot cfg a little bit and is working like a charm, where is the concrete difference with the lemaker?
